I want to convert the large datetime data into double format.
I used datenum command, but its changing the value. The code and the values are attached below. Here TimestampHide is the data from an excel sheet.
MATLAB Code:
>> T=TimestampHide;
>> T.Format = ‘yyyy-MM-dd HH:mm:ss.SSS’;
>> Z=datenum(T);
The value of ZI used datenum command, but its changing the value. The code and the values are attached below. Here TimestampHide is the data from an excel sheet.
MATLAB Code:
>> T=TimestampHide;
>> T.Format = ‘yyyy-MM-dd HH:mm:ss.SSS’;
>> Z=datenum(T);
The value of Z I used datenum command, but its changing the value. The code and the values are attached below. Here TimestampHide is the data from an excel sheet.
MATLAB Code:
>> T=TimestampHide;
>> T.Format = ‘yyyy-MM-dd HH:mm:ss.SSS’;
>> Z=datenum(T);

Matlab function only giving me 1 output
I have a function but its only giving me 1 output as an answer.
>> theta = 0:0.01:90;
>> Vmax = sqrt((0.25.*cos(theta).*9.8.*(sin(theta)+0.2.*cos(theta)))/(cos(theta)-0.2.*sin(theta)))
Vmax =
0.1514
I want to plot this on a graph but it only interprets the function as having 1 value. I’ve done functions this way before like if i just say
>> x = 0:0.01:pi;
>> y = sin(x);
it works fine so why is my Vmax just giving me 1 value.I have a function but its only giving me 1 output as an answer.
>> theta = 0:0.01:90;

Error when buliding PX4 firmware with some deactivated modules
Dear all,
I am currently using simulink to impememt my filght controller into Pixhawk 6x. At the step of building PX4 firmware I followed this tutorial https://ch.mathworks.com/help/uav/px4/ug/disable-control-modules.html. to avoid flash memory overflow issues, since building a default PX4 firmware itself takes already 99% of the total flash usage.
I change the code
CONFIG_MODULES_MC_ATT_CONTROL=y
to
CONFIG_MODULES_MC_ATT_CONTROL=n
in the file default.px4board.original and resave it as a new file hil.px4board. in the same folder.
In the Hardware Setup screen I tried to build ths new firmware but there is then an Error in cmd window,saying:

Have you met this issue before and how did you solve it?
any suggestions or advices are welcome.

Y.Z. Dear all,
I am currently using simulink to impememt my filght controller into Pixhawk 6x. At the step of building PX4 firmware I followed this tutorial https://ch.mathworks.com/help/uav/px4/ug/disable-control-modules.html. to avoid flash memory overflow issues, since building a default PX4 firmware itself takes already 99% of the total flash usage.
I change the code
CONFIG_MODULES_MC_ATT_CONTROL=y
to
CONFIG_MODULES_MC_ATT_CONTROL=n
in the file default.px4board.original and resave it as a new file hil.px4board. in the same folder.
In the Hardware Setup screen I tried to build ths new firmware but there is then an Error in cmd window,saying:

Looking for help with labelling groups
Hey everyone,
so far I’ve read all Matlab entrys on adding/creating categories and/or labels but I haven’t found something fitting that works for me. I have a set of data in 178×13 double format, the variable names in a 1×13 cell format and the group classification in a 178×1 double, which ist just 1 2 and 3. In different projects I had a 178×1 cell instead containing the names of the groups and I would use that to generate a double using findgroups. However, now I would like to do the reverse action and generate a 178×1 cell value with the names instead of numbers. Num2Cell does not work here of course because I would like to tell Matlab to put "GroupA" for every 1 in the group classification 178×1 double and "GroupB" for every 2 and GroupC for every 3. I have information that the first 59 belog to GroupA etc, but I don’t know how to implement that either. Maybe it’s the language barrier but I really don’t even know what to search for anymore. Any help is much appreciated!Hey everyone,

Control quiver arrow head width vs height.
Hi, I have a quiver plot where the arrow heads are incredibly wide by default, so I used "MaxHeadSize" to shrink them to a reasonable size. Also, the scaling behavior is set to 0 because I want them to connect the way they do currently. The downside is that now, instead of looking like arrowheads, they almost look like horizontal bars. I’m wondering if there is a way to control the head length independently of the head width.Hi, I have a quiver plot where the arrow heads are incredibly wide by default, so I used "MaxHeadSize" to shrink them to a reasonable size.

Create a generic x for (x,y) plot
I’m not well versed in matlab at all so hopefully this post makes some sense.
I have tons of data in .txt files that I want to plot.

Simulink Debug brings up two Visual studio sessions
I ran into issues when trying to debug c caller code in simulink. environment: Matlab 2022a, Visual Studio Community 2019.

Colon operands must be real scalars
I tested the following code:
x = rand(1,3);
x([1,2]:[1,2])
In R2024a it gives a warning but it is ok in R2023b! Some existing code that I use relies on this feature. Any reason why it will become an error in the future?

Heatmap doesn’t show the values
The heatmap figures I used to plot on Matlab had the values labeled in each cell (just like the documenation says), but now the figure doesn’t include the text. I’m not sure if I made changes to some settings. Does anyone know what the issue is?
For instance, I get the correct output here, when I run the following on web.

Multiplication of a Sparse Matrix With Diagonal Matrices
I have a sparse m x m square matrix L (which is actually a Laplacian matrix of a large graph) and an m x1 vector d. I want to create a diaognal matrix D whose diagonal is populated with the entries in d and then generate
normL = D * L * D

D = spdiags(d, 0, m, m)

I wonder whether there is a more efficient way to do this given that the (i, j)-th elements of normL and L are related by
normL(i, j) = D(i) * D(j) * L(i, j).

Import geopolyshape from gdb fails
Hi,
I’m completly new to Matlabs.
I’m trying to load my buildings into the siteviewer, to create a rf propagation in the end.
But I just can’t get my buildings to load. My features are in a esri .gdb an in the coordinate system is WGS_1984.
The features are 3d buildings and are of the type esrie multipatch. The level of detail is only 1, so LOD1 (building blocks without roof).
Code to load:
geo = readgeotable("D:Arbeit3D_Ausleuchtung3D_AusleuchtungDatenDaten_1.gdb", CoordinateSystemType="geographic");
viewer = siteviewer(Buildings=geo, Basemap="topographic");
If I try to load these into the siteviewer I get the following error:
"Error using siteviewer
The coordinates of the input points must be finite values; Inf and NaN are not permitted."
I tried converting the features to kmz an import them, but the error is still the same.
I managed to load the sideviewer with only one feature out of my buildings. So some features are OK, some not to import into sideviewer.
All my features are fine in other gis, like arcgis pro or qgis.
But the one building I can load is floating, I don’t know if this is beacause no terrain moddel is loaded or if there is a property to map them to the ground.
Can anyone help me or give me a hint in the right direction?
thanks, sebastianHi,

If I try to load these into the siteviewer I get the following error:
"Error using siteviewer
The coordinates of the input points must be finite values; Inf and NaN are not permitted."
I tried converting the features to kmz an import them, but the error is still the same.
I managed to load the sideviewer with only one feature out of my buildings. So some features are OK, some not to import into sideviewer.
All my features are fine in other gis, like arcgis pro or qgis.
But the one building I can load is floating, I don’t know if this is beacause no terrain moddel is loaded or if there is a property to map them to the ground.
Can anyone help me or give me a hint in the right direction?
thanks, sebastian geo, geopolyshape, antenna, gdb, readgeotable MATLAB Answers — New Questions
atan2 does not accept complex numbers as input
Good Morning
If I’m not mistaken I think that there is a definition of the atan2() function also in the complex field.
If so , It is possible to implement a complex version of the atan2() function ?
i mean in a way that i can compute atan2(a+i*b , c+i*d) , where a,b,c,d are real and i =sqrt(-1) ,
this both numerically and symbolically
thankyou 🙂
Kind regards

Sending information to MATLAB from Python via TCP
I want to send data from Python to MATLAB every 10 seconds via TCP. The code I have works for the first iteration of the loop, but on the second iteration we reestablish the connection, yet the data fails to send.
The relevant Python code is:
import socket
import sys
import time
%Create a TCP/IP socket
i = 0 %loop counter
j=45.395 %data to be sent to MATLAB
while i < 1000:
with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:
s.bind((‘localhost’, 51001))
s.listen(1)
conn, addr = s.accept()
print(f"Connected by {addr}")
conn.sendall(bytes(str(j), ‘ASCII’))
conn.close()
i+=1
j+=0.6
time.sleep(10)
The MATLAB code is
i=0;
while i < 1000
t = tcpclient(‘localhost’, 51001);
output = read(t);
data = char(output(1:4));
pwrcmd = str2double(data);
fprintf(‘%f’, pwrcmd);
clear t;
i = i+1;
pause(10)
end
and finally the output on the terminal is:
>python matlab_connect_test.py
Connected by (‘127.0.0.1’, 56010)
Connected by (‘127.0.0.1’, 56012)
The first thing I tried was to establish just one server-client connection, and send data every 10 seconds through that one connection, rather than reconnecting every 10 seconds. That was unsuccessful. For some reason even though the second connection is established, MATLAB never receives the second value of j, or any subsequent values. Any help would be very much appreciated.I want to send data from Python to MATLAB every 10 seconds via TCP.

Dear all, may I know how can we enter the extinction coefficient value in Stk?
I’m using STK system tool kit with matlab and in the laser environment we can use Beer-Lambert law by adding the extinction coefficient so suppose we have a cloud causing attenuation equals 1.2dB/km,how can I enter this value in the extinction field field in Stk, it has to be in m-1 and I have to identify the layer top.I’m using STK system tool kit with matlab and in the laser environment we can use Beer-Lambert law by adding the extinction coefficient so suppose we have a cloud causing attenuation equals 1.2dB/km,how can I enter this value in the extinction field field in Stk, it has to be in m-1 and I have to identify the layer top.
