After having used the command “appdesigner” at command window:When an app is running at app designer the same app is automatically running at the main window too.
After having used the command "appdesigner" at command window, the behavior of Matlab changed. Now on I can’t run an application at app designer and at same time run another script at main window. Both windows run the same programm whichever starts first. When an app is strating running at app designer the same app is automatically running at the main window too and vice versa. I used Matlab 10 hours a day 3 months ago with no such behavior: I cant run an app at app designer , stop it at a breakpoint and then use the main window to run a script searching at app variables etc any more.
Thankls in advance.After having used the command "appdesigner" at command window, the behavior of Matlab changed.

RoadRunner HD Map create
I finished the example of compiling a protobuf file into c++ to generate a rrhd file.
But here, I tried to build the section I selected, but lane and lane boundary didn’t understand how to express the curve, how to specify the coordinates, etc., and I couldn’t find it.
Do I have to create a hd map from a compilation of protobuf files into c++??
I tried to create with matlab, but I couldn’t find a way to add a lane or express it as a curve.

MatLab C++ Shared Dll library initialization problem
I am using Matlab 2013a and Visual Studio 2013. I am trying to use MatLab compiled dll from a C++ console application. My simple Matlab test dll and console application is compiled for 64bit machines (I made sure they are 64bit via dumpbin). I also have correct version of MCR installed on my machine (even if it’s not necessary).
I setup my compiler using "mbuild -setup" command.
I compile my .m file using this command line: "mcc -v -W cpplib:mylib -T link:lib myFunc" successfully.
In my console application, I include these libraries: mylib.lib, mclmcrrt.lib, mclmcr.lib, libmx.lib, libmat.lib
and use the libraries in this path "C:Program FilesMATLABR2013aexternlibwin64microsoft"
When I debug my program, it successfully initializes MCR using this call: "mclInitializeApplication(NULL, 0)" but when I call
"mylibInitialize()" in order to initialize my library, program crashes. It doesn’t even throw an axception therefore I cannot handle it using
try/catch block. It gives unhandled exception and access vialoation error message.
These are sample debug output messages I got;

How can I extract the numerical array from a hypercube object?
Hi! I’ve been using the hyperspectral library for the image processing toolbox for some years now. In the beggining, when a variable of class hypercube was created, it was storing the nomerical array (i.e. the spectral image) in a struct way that you could acces via dot indexing, for instance:
spectral_image = cube.DataCube;
However this seems not to be working anymore. Instead if I try this, I get a string instead of a numerical array. I’ve cheked and there is a funcion called gather which is supposed to be for this. I have also tried:
spectral_image = gather(cube);
But it is also not working. I get the following error, but my spectral image fits more than enough in my RAM, so I am sure this is not a problem.
Dot indexing is not supported for variables of this type.
Error in hypercube/gather (line 1398)
if isa(obj.BlockedDataCube.Adapter,’images.blocked.InMemory’)
^^^^^^^^^^^^^^^^^^^^^^^^^^^
The problem is that I have spectral images stored in files in hypercube class that I saved some time ago with Matlab R2023 version or even earlier, but now I can not access directly to this numerical arrays that previously were perfectly fitting in my RAM.
Any clue about how could I fix this?

power spectral density of nonstationary data
I am hoping those with seasoned experience with signaling can assist me with two questions. The ultimate goal is to obtain a power spectral density of very nonstationay optical data sampled at 1 kHz (attached). There is a huge DC offset that persists even after detrending or subtracting the mean. For such nonstationary data, pwelch seems most appropriate but a rather odd looking series of deminishing regularly space peaks is outputted across the frequency domain. Is the windowing wrong? Is this the wrong analysis to do?
First, here is the pwelch based code I ran:
x = time_series – mean(time_series);
fs = 1000;
[pxx_smooth, f] = pwelch(x, hann(length(x)/2), [], fs);
figure;
plot(f, 10*log10(pxx_smooth), ‘LineWidth’, 1.5);
If you run the code on the attached time-series you get no distinct peaks and a huge off wtih a very narrow frequency domain. This makes no sense.
Second, despite supposedly not correct to do since this is non-stationary data, I ran an FFT:
fs = 1000;
%x = detrend(time_series);
x = time_series-mean(time_series);
figure;
L = length(x);
plot(fs/L*(-L/2:L/2-1),abs(fftshift(x)),"LineWidth",2)
With an FFT you get more defined peaks and over a much larger frequency range (see attached jpg), but confused why the asymmetry when using ffshift, where it should be symmetrical about x = 0. Why the asymmetry?
I am convinced I doing something fundamentally wrong with the processing or windowing and odd looking output is not inherently due to the data itself. Any assistance in how to correctly attain a PSD for this data and what is the most valid approach for nonstationary data of this nature would be greatly appreciated.I am hoping those with seasoned experience with signaling can assist me with two questions.

PWM on PE5 / PE6 causes XCP error on NUCLEO-H753ZI in Simulink (STM32 support package)
Hi everyone,
I am migrating a Simulink model from NUCLEO-F767ZI to NUCLEO-H753ZI using the Simulink Support Package for STM32.
Most peripherals work correctly on the H753ZI:
>I2C
>UDP / Ethernet
>PWM on other pins
However, I am facing an issue specifically with PWM outputs on pins PE_5 and PE_6.
>>Setup details:
Board: NUCLEO-H753ZI
MCU: STM32H753 (single-core Cortex-M7)
Toolchain: Simulink + STM32 support package
PWM pins: PE_5 and PE_6
These pins are mapped to TIM15
PWM configured as PWM Generation CH1 (not CH1N)
>>Observed behavior:
When PWM blocks for PE_5 and PE_6 are disabled, the model builds, downloads, and runs normally.
When PWM on PE_5 and/or PE_6 is enabled, the model fails to run:
An XCP error is reported immediately
The application does not start execution on the target
PWM on other pins works correctly.
The same Simulink model worked without issues on the F767ZI.
This appears to be specific to STM32H7 .
Any insights or recommendations would be greatly appreciated.

How do I choose the poles and zeros in order to calculate my TF from input & output data?
Hello :), I have a set of data exported from my simulator, which consists of Thrust getting in the system (T_in) and some Thrust output after some conversions (T_out) for two different types of propellers, HTU and DEP. I use iddata to package the output, input and sample data.
Then with that data I use tfest to estimate the continuous-time transfer function sys.
My problem is that I don’t know how to define the number of poles (np) and zeros (nz). Any suggestions?
Thanks in advance!

title(‘Bode Diagram for DEP System’);Hello :), I have a set of data exported from my simulator, which consists of Thrust getting in the system (T_in) and some Thrust output after some conversions (T_out) for two different types of propellers, HTU and DEP. I use iddata to package the output, input and sample data.
Then with that data I use tfest to estimate the continuous-time transfer function sys.
My problem is that I don’t know how to define the number of poles (np) and zeros (nz). Any suggestions?
Thanks in advance!

How to install symbolic toolbox if I have a student version of matlab
Hi! I have a student version of Matlab, and I need to use symbolic toolbox, but I don’t know how to go about installing it. I know that it was included, but I am not sure how to get to it. Very basic step by step instructions would be appreciated.Hi! I have a student version of Matlab, and I need to use symbolic toolbox, but I don’t know how to go about installing it.

how to represent schottky diode in matlab simulink
I am trying to simulate a maximum power point tracking algorithm where i integrate it with a boost converter. the schematic i will be implementing involves a schottky diode, which does not exist as a simulink block. the only online resource for a schottky diode is actually a zener diode, which it looks like someone made by adjusting the masking of the diode block to connect to an actual part. what is the simplest way for me to create a schottky diode block? the resource with zener diode that I am talking about: https://www.mathworks.com/help/sps/ug/schottky-barrier-diode-characteristics.htmlI am trying to simulate a maximum power point tracking algorithm where i integrate it with a boost converter. the schematic i will be implementing involves a schottky diode, which does not exist as a simulink block. the only online resource for a schottky diode is actually a zener diode, which it looks like someone made by adjusting the masking of the diode block to connect to an actual part. what is the simplest way for me to create a schottky diode block? the resource with zener diode that I am talking about: https://www.mathworks.com/help/sps/ug/schottky-barrier-diode-characteristics.html I am trying to simulate a maximum power point tracking algorithm where i integrate it with a boost converter. the schematic i will be implementing involves a schottky diode, which does not exist as a simulink block. the only online resource for a schottky diode is actually a zener diode, which it looks like someone made by adjusting the masking of the diode block to connect to an actual part. what is the simplest way for me to create a schottky diode block? the resource with zener diode that I am talking about: https://www.mathworks.com/help/sps/ug/schottky-barrier-diode-characteristics.html energy harvesting, simulink MATLAB Answers — New Questions
What qualifies as research to have to get the commercial license?
I would like to use Matlab for modeling (not to gather data but simply organize it). Does that mean I have to change my home license to a commercial one? I’m not affiliated with a university yet. Not sure if that qualifies as research if it only aids it.I would like to use Matlab for modeling (not to gather data but simply organize it).
