How to properly make a circular histogram?
I have data points which are the angle and distance around a central point. I would like to make a histogram of these points so I can visualise their distribution and also perform some analyses on their density etc.
For now, I make a 2D histogram, treating the data points as if they are cartesian X,Y coordinates. I then transform the bin centers into polar coordinates and replot the data, like this:
% create data points
theta = normrnd(0,0.5,1000,1);
rad = 100.*rand(1000,1);
figure
subplot(1,3,1)
polarscatter(theta,rad,10,’k’,’filled’,’o’)
title(‘data points’)
% prepare bins
theta_bins = linspace(-pi,pi,120);
rad_bins = 0:5:100;
% ‘normal’ histogram
f = histcounts2(rad,theta,rad_bins,theta_bins);
subplot(1,3,2)
imagesc(f)
daspect([1 1 1])
title(‘histogram in cartesian coordinates’)
% transform bin coordinates
[theta,rad] = meshgrid(linspace(min(theta_bins),max(theta_bins),length(theta_bins)-1),linspace(min(rad_bins),max(rad_bins),length(rad_bins)-1));
[X,Y] = pol2cart(theta,rad);
subplot(1,3,3)
s = surf(X,Y,f);
s.EdgeColor = ‘none’;
view(0,90);
daspect([1 1 1])
axis xy
title(‘histogram in polar coordinates’)
However, the resulting histogram is not really ideal – the bins are not homogeneous because they get larger as the radius increases. This is due to the fact that I made the histogram in a cartesian reference frame.
I was wondering if there is a better way to go about this? Some sort of circular histogram with circular bands of triangular bins? Or hexagonal bins? Can anyone suggest anything?

How to define input parameters for BytesAvailableFcn (tcpclient)
Hy all,
my problem concerns the use of input arguments when I define the BytesAvailableFcn of a tcpclient connection.
I create a tcpclient connection:
t = tcpclient(‘address’, port);
And I send a request to the server (which starts automatically to send data):
write( t, ‘request’ );
I want to have a callback function triggered by a bytes available event:
configureCallback( t, "terminator", @MyCallbackFcn );
MyCallbackFcn is written in a separated MyCallbackFcn.m file. The callback function MyCallbackFcn is triggeredd whenever a terminator is available to be read from the remote host specified by the TCP/IP client.
At the moment, MyCallbackFcn uses global parameters (var1, var2, etc.) defined in the main program:
function MyCallbackFcn( src, ~ )
global var1 var2
…
end
This algorithm works well. But in order to avoid the use of global parameters, I would like to define input parameters for MyCallbackFcn fonction. My problems start here, because I do not find the right form to write:
the definition of the callback function in the main program : configureCallback( t,…
the function MyCallbackFcn in the MyCallbackFcn.m file
Thank you in advance for your help.

MATLAB Coder: C Version Much Slower Than Mex Version
I used MATLAB Coder to turn my MATLAB code into C code and expected a great decrease in run time, but instead found that my C code runs much slower than both the MATLAB code and the mex code. Over 5 tests, I get the following:
Tthe MATLAB code took 77.48 seconds on average.
The mex version running in MATLAB took 46.27 seconds on average.
The generated C code took 262.35 seconds on average.
All three versions of the code produces the exact same output, so I am confident that each version is working properly. I am running the MATLAB and mex versions in R2023a and the C version in Debian 11 (bullseye) in a docker container. The cmake command I am running is
cmake -DCMAKE_BUILD_TYPE=Release ..
and my understanding is that this enables the C compiler optimisations, but I’m unsure if there are further optimisations I can enable. Before specifying the build type as release, my C code ran about 90 seconds slower still (~350s), which is horrendous compared to the MATLAB/mex version.
These are the settings I am generating my code with:
The full settings I used are attached in config.mat but they are almost all just the default settings.
My understanding is that MATLAB does some computations in parallel automatically, while the generated C code doesn’t, so I tried turning on automatic parallelisation in the generated code. This only made the code run slower, however. I’m not sure how the automatic paralellisation works, but when I manually tried to parallelise parts of my code, it also did not run faster, so I did not really expect this to improve anything.
I’m just really unsure why the C version runs so much slower than even the mex version, which I expected to be similar or worse than the C version. Are there settings I can tweak in Coder? Are there further optimisations I can enable on the Linux side of things? If this is normal behaviour, what is the explanation for the discrepency between C and mex?I used MATLAB Coder to turn my MATLAB code into C code and expected a great decrease in run time, but instead found that my C code runs much slower than both the MATLAB code and the mex code.

Battery Pack Modeling – Self-Paced Online Course – Unable to Proceed Further due to Problem in Task 4 in the exercise “Exploring the Custom Battery Pack Block”
Hello, I have recently started learning about Battery Pack Modelling using Simulink/Simscape through the "Battery Pack Modelling" Self-Paced Online Course offered by MathWorks. I am taking the course through the Chrome Browser (Simulink Online) for the simulinkR2024b version.
Presently, I am facing an issue under Section 2.1 – Pack Modelling of this course due to which my progress has come to a halt. The problem I am experiencing is related to Task 4 in the exercise "Exploring the Custom Battery Pack Block" of the particular section I mentioned above. I am unable to proceed ahead with the completion of the exercise as the "Training Assessment" fails each and every time I click the submit button even though I have clearly and carefully followed the instructions provided and completed the given task.
To give a brief summary and clarify the context, in Task 4, we have to observe the battery voltages in the simulation. We have to start by right-clicking the batteryVoltage port of the Battery Pack and selecting Log Selected Signals. Next, we have to change the Stop Time in the Simulate section to 200. After that, we have to navigate to the Simulation tab and click Run to execute the model. Once the simulation is complete, we have to access the Data Inspector from the Review Results section. The Simulation Data Inspector window appears, and we have to click and select NewPack(8). A dialog box titled Multidimensional Signal appears, where we have to select Convert to channels (24) and then choose NewPack (1,1) and NewPack (10,1) to view the battery voltages.
Now the difficulty I encountered while performing the task is that after running the simulation and opening up Data Inspector from the Review Results section, I am not shown the option of NewPack(8) as mentioned in the instructions and instead shown NewPack:3 (8). Also, when I click and select NewPack:3 (8), I am not presented with the option of Convert to channels (24) and instead presented with Convert to channels (8). As a result, there are no options such as NewPack (1,1) and NewPack (10,1) to select in order to observe the battery voltages. I believe the "Training Assessment" fails when I click submit because I don’t meet the criteria specified in the instructions. However, despite re-running the task multiple times, I consistently receive the same set of options to select, not the ones specified in the task instructions. Hence, I am unable to proceed further.
Could someone verify whether there are any problems with the assessment or the proposed solution?

Adjusting sample rate in Simulink model to reflect transition from bitrate to symbol rate
I am trying to build a simple communication system in Simulink. I want to simulate a bit source that generates bits with a specific sample rate (bit rate). I then buffer the generate samples into frames of 1008 bits. For application specific reasons I then pad the frame with 16 zeros to a total of 1024 bits. The goal is then to BPSK modulate the bits and output the generated symbols at a specific symbol rate different to the bit rate.
The goal is that the spectrum analyzer shows a spectrum that reflects the intended symbol rate.
I have problems implementing this and I am confused about how Simulink handles frame time/sample time. Sample time in Simulink is defined as the rate at which a block generates output. So far so good, but I still want to enforce a specfic real sample time, i.e., time between consecutive samples (NOT frames).
Problem 1
Using the Vector Concatenate block for zero padding effectively seems to upsample the signal and the sample time in the resulting frame is smaller than the bitrate/sample rate specified in the bit source. I am using a Frame Transition block to remedy this where I specify the sample time (this is ambigous this specifies the frame time due to the Simulink sample time definition) property as (Frame_Size+16)*bit_rate. This does not seem to work as the output frames of the Rate Transition block is somewhat unpredictable. However, when placing a spectrum analyzer directly after the first Rate Transition block, the sample rate that is displayed in the spectrum analyzer shows the intended sample rate = bit_rate (10 kHz).
Problem 2
After the BPSK block I placed another Rate Transition Block to generate symbol frames where each symbol is output at a specific symbol rate. In my case the symbol rate is bit_rate/10. The spectrum analyzer shows the desired sample rate (1kHz). (see image below)
BUT: again, the output frames of the second Rate Transition block do not show the desired behaviour. I want it to buffer the incoming frames and output them at a slower rate. What happens though, is that the Rate Transition block subsamples the input and outputs every 10th frame and drops the other frames.
Any help is greatly appreciated! Thanks!I am trying to build a simple communication system in Simulink. I want to simulate a bit source that generates bits with a specific sample rate (bit rate).

After the BPSK block I placed another Rate Transition Block to generate symbol frames where each symbol is output at a specific symbol rate. In my case the symbol rate is bit_rate/10. The spectrum analyzer shows the desired sample rate (1kHz). (see image below)
BUT: again, the output frames of the second Rate Transition block do not show the desired behaviour. I want it to buffer the incoming frames and output them at a slower rate. What happens though, is that the Rate Transition block subsamples the input and outputs every 10th frame and drops the other frames.
Any help is greatly appreciated! Thanks! I am trying to build a simple communication system in Simulink. I want to simulate a bit source that generates bits with a specific sample rate (bit rate). I then buffer the generate samples into frames of 1008 bits. For application specific reasons I then pad the frame with 16 zeros to a total of 1024 bits. The goal is then to BPSK modulate the bits and output the generated symbols at a specific symbol rate different to the bit rate.
The goal is that the spectrum analyzer shows a spectrum that reflects the intended symbol rate.
I have problems implementing this and I am confused about how Simulink handles frame time/sample time. Sample time in Simulink is defined as the rate at which a block generates output. So far so good, but I still want to enforce a specfic real sample time, i.e., time between consecutive samples (NOT frames).
Problem 1
Using the Vector Concatenate block for zero padding effectively seems to upsample the signal and the sample time in the resulting frame is smaller than the bitrate/sample rate specified in the bit source. I am using a Frame Transition block to remedy this where I specify the sample time (this is ambigous this specifies the frame time due to the Simulink sample time definition) property as (Frame_Size+16)*bit_rate. This does not seem to work as the output frames of the Rate Transition block is somewhat unpredictable. However, when placing a spectrum analyzer directly after the first Rate Transition block, the sample rate that is displayed in the spectrum analyzer shows the intended sample rate = bit_rate (10 kHz).

Windows Account Sync Known wifi Network at Device level
Hi All,
I am facing issue with Windows Account sync known wifi settings. This happen in the environment as feature enabled on Windows Account Settings.
Example: New Device issue to end user and when user take this home. Home wifi is connected automatically without entering the Home wifi Password.
Bug/Security Issue: If this was a loan laptop and Next User login to the device. This user go to known wifi Network. Under known wifi networks. Second user will see all his known wifi and known wifi of First User whom this laptop was issued. Also he can see the password of Known saved Wifi of First User.
Observation: Known wifi information is saved/synced at device level after login to Device. Instead this information should be saved at User Level.
Any suggestions are welcome!!

Why can’t we define properties on enumerations extending from built-in classes?
Trying to understand why we can’t subclass something like a uint8 and add a property. Say I want to enumerate data types and conveniently bundle the size of instances of the type in bytes.
In this first case, we specify which uint8 we want each enumeration member to correspond to in parens next to the name, and this works fine:
classdef DataTypeEnumeration < uint8
enumeration
UINT8 (0)
UINT16 (1)
UINT32 (2)
UINT64 (3)
end
end
In totally user-defined classes we use these parens to set properties, like
classdef DataTypeEnumeration
properties
underlying_value
end
enumeration
UINT8 (0)
UINT16 (1)
UINT32 (2)
UINT64 (3)
end
methods
function obj = DataTypeEnumeration(v)
obj.underlying_value = v
end
end
end
but it does not seem there is any way to use this syntax for the built-in type, even if I am not actually trying to define a new property:
classdef DataTypeEnumeration < uint8
properties
some_special_underlying_value_property
end
enumeration
UINT8 (0)
UINT16 (1)
UINT32 (2)
UINT64 (3)
end
methods
function obj = DataTypeEnumeration(v)
obj.some_special_underlying_value_property = uint8(v)
end
end
end
or even just
classdef DataTypeEnumeration < uint8
enumeration
UINT8 (0)
UINT16 (1)
UINT32 (2)
UINT64 (3)
end
methods
function obj = DataTypeEnumeration(v)
obj = uint8(v)
end
end
end
seems like it should work. It kind of feels like the only reason we can’t tack on a property to an enumeration of some built-in type is because the interface doesn’t support it, which would be sad. What would be the harm in being able to let the parent object be constructed with the first argument and set properties with following arguments, like
classdef DataTypeEnumeration < uint8
properties
bytes
end
enumeration
UINT8 (0, 1)
UINT16 (1, 2)
UINT32 (2, 4)

Optimal control of SEIR with RK4 method problem on updating
Hello everyone,
I am trying to implement an optimal control problem using Runge-Kutta 4th order for a SEIR model with two different categories. My code is running and provides an optimal control but the state variables S,E,I and R remain as if no intervention occurs, which means that the update of the second part is somehow not implemented in it? I don’t understand where is the problem. I ran it some times and the results were fine but then all of a sudden it just gives me S,E,I and R as if no control is imposed on the model. Can you please have a look? code follows

end Hello everyone,
I am trying to implement an optimal control problem using Runge-Kutta 4th order for a SEIR model with two different categories. My code is running and provides an optimal control but the state variables S,E,I and R remain as if no intervention occurs, which means that the update of the second part is somehow not implemented in it? I don’t understand where is the problem. I ran it some times and the results were fine but then all of a sudden it just gives me S,E,I and R as if no control is imposed on the model. Can you please have a look? code follows

October 1st 2024 minimum 5 characters username techcommunity
My username is ElB and if I understand correctly, a username must be at least 5 characters from October 1st. If not, I thought I read that the history of your account would disappear.
Yesterday (October 27th) I happened to get this information by clicking on this link in an email https://techcommunity.microsoft.com/t5/planner-blog/task-management-tips-for-planner-beginners/bc-p/4255599#M2525 I don’t see this information about this restriction anywhere anymore and I can’t reproduce it anymore.
I find it strange that this important information with its great impact can now not be found anywhere easily and quickly. Even in my profile I don’t get a notification and information!
Who knows more about a required 5-character username starting October 1, 2024? Please provide a source!

Write Stream Binary Header with different precisions
I want to write a stream binary file that has different precisions for the header. Below is the header that I want to include with 256 Characters for the name of the file, double precision for the number of rows and columns, and then the data set is single precision.
256 Character -> "Unformatted file version=292498251"
Double -> "13"
Double -> "1000000"
Single -> "data" which is an array with 1000000 x 13 entries
Any help would be appreciated!I want to write a stream binary file that has different precisions for the header. Below is the header that I want to include with 256 Characters for the name of the file, double precision for the number of rows and columns, and then the data set is single precision.

Curve fitter limitation for equations in the form f(x,y)=a*x^n/(y+b)^m
Dear Community Members,
When I use curve fitter for equation in the form f(x,y)=a*x^n/(y+b)^m, the results are very bad (R-square is very, very low).
After removing "b" or changing it with a random number (for example 8, then f(x,y)=a*x^n/(y+8)^m), R-square is very good.
The question is: Is this a limitation of the software or there is a way to overcome this problem and to use "b", which value wiil be calculated by Curve fitter.Dear Community Members,
