unique across tables within table
Hello
I’ve got what in the screenshots below, so RawFileIndex is a table that contains Paramaters that is another table (or a 1×1 cell containing a table? I’m a bit confused…)
I want to know all the parameter ID accross all the files, something like unique(RawFileIndex.Parameters{:,1}.ID) but this is clearly not the right syntax… how do I do it?
thanksHello

Updated Matlab keep trying to update
Hi,
I have Matlab installed on Debian 12 and 4 days ago I update the installation to the last available version.
I usally works from the command line meaning that I open Matlab using
matlab -nodesktop -nosplash
I’ve been working like these for years.
However, lately at random moments I got a message saying: "Launching updater executable" on the command windows. Checking the monitor of resources there is process called "InstallMathWorksService Host" which is using 100% of one of my CPUs.
However, when I open the GUI and try to update Matlab says it’s up to date. Even if I close Matlab in the command windows, I still got the message about "launching update" randomly.
What can I do?

How to get input from a simulink model to .m file ?
I made a simulink model and linked it with interpreted matlab function block which has my .m code file, but I need 6 inputs to the .m file that are supposed to come from my model.

Inputs and process for thermal model discretization for battery spatial temperature estimation
Hi,
I am building a cell and module level battery model. I am using ECM for electrical model and want to use 3D discretized thermal model which I am building in Ansys.
Is there a way to connect this thermal model from ansys to simscape for spatial temperature distribution analysis? Also, if possible, how can it be done on a module level?
I am refering this example – https://www.mathworks.com/help/simscape-battery/ug/battery-spatial-temperature-variation-during-fast-charge.htmlHi,

I have a set of grided wind data (lat, lon, windspeed) that I am processing. Data is grided every 0.11deg between (0-60Deg South and 50-190Deg E) and I want to find the max wind inside a circle of say 30km. How can I do this?Hi and thanks in advance.

Errors integrating Arduino C++ code into Simulink using S-Function Builder
Hi all,
I am currently attempting to integrate Arduino C++ code into my Simulink model using the S-Function builder. I am starting simple by essentially following this tutorial line for line to create a custom function that writes HIGH to a pin of choice on the Arduino board. I had a decent amount of success at first following the tutorial. I am able to compile functions written into C to Matlab executables, and even integrate them into my model to do things like basic things like double an input signal without any errors. However, I have issues as soon as I try to call functions from the standard Arduino library. Here is my header for the S-Function Builder:
/* Includes_BEGIN */
#include <math.h>
# ifndef MATLAB_MEX_FILE
# include <Arduino.h>
# endif
/* Includes_END */
Again, this is just following the guide I linked earlier. This S-Function also successfully builds and compiles into a Mex file, but when I try to run this model in Simulink using Monitor and Tune, I am slammed with dozens of error messages. Most the error messages however are basically identical, they either look like this:
C:/ProgramData/MATLAB/SupportPackages/R2023b/aIDE/hardware/arduino/avr/cores/arduino/Arduino.h:137:16: error: unknown type name ‘uint8_t’; did you mean ‘uint8_T’?
int analogRead(uint8_t pin);
^~~~~~~
uint8_T
Or like this:
C:/ProgramData/MATLAB/SupportPackages/R2023b/aIDE/hardware/arduino/avr/cores/arduino/Arduino.h:170:30: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘digital_pin_to_bit_mask_PGM’
extern const uint8_t PROGMEM digital_pin_to_bit_mask_PGM[];
^~~~~~~~~~~~~~~~~~~~~~~~~~~
At first I thought this was because I was trying to call C++ functions from a C source file. The workaround to this seems to be to rename the wrapper function file to have .cpp file extension, and insert ‘extern "C"’ before the two function declarations in the file. However after trying this fix, I just get this error message after running in Simulink:
Unable to find S-function module ‘example_wrapper.c’. S-function modules must exist as either source files or pre-compiled object files on the MATLAB path.
This is an error I have not seen other users come into and I am a bit lost where to go from here. I have tried setting the target language to C++ in the S-Function builder instead of inherit from model, but when trying this am I hit with the dozens of same error messages as before. Is there a better way to integrate C++ and Arduino libraries into my model than the S-Function builder? Any help is much appreciated.Hi all,

extern const uint8_t PROGMEM digital_pin_to_bit_mask_PGM[];
^~~~~~~~~~~~~~~~~~~~~~~~~~~
At first I thought this was because I was trying to call C++ functions from a C source file. The workaround to this seems to be to rename the wrapper function file to have .cpp file extension, and insert ‘extern "C"’ before the two function declarations in the file. However after trying this fix, I just get this error message after running in Simulink:
Unable to find S-function module ‘example_wrapper.c’. S-function modules must exist as either source files or pre-compiled object files on the MATLAB path.
This is an error I have not seen other users come into and I am a bit lost where to go from here. I have tried setting the target language to C++ in the S-Function builder instead of inherit from model, but when trying this am I hit with the dozens of same error messages as before. Is there a better way to integrate C++ and Arduino libraries into my model than the S-Function builder? Any help is much appreciated. arduino, s-function, simulink, embedded coder MATLAB Answers — New Questions

How can I call a matlab function that takes no arguments using matlab engine C++ API?
I have a matlab function (myFunc) that takes no arguments and returns a matlab string. I want to call this function using the matlab engine C++ API. In all examples I have found in documentation, the functions used receive at least one argument (like sqrt o gcd). I have tried declaring an empty variable and using it like this:
const matlab::data::Array arg;
auto res = matlabPtr->feval(u"myFunc", arg);
The code compiles OK, but when I run it I get the exception error "Default constructed arguments are not allowed"
Is there a way to call this kind of function?

How to implement custom function in Flight Log Analyzer
I am trying to create a custom function within the Flight Log Analyzer app in the UAV Toolbox, and I am getting errors no matter what I try. I am simply trying to plot a Fast-Fourier Transform of Accel and Gyro data. Below is an example of a function I wrote that works on its own, but I can not get it to work within the app. I am wondering what the function sturcture is that the app is looking for. I see what is on the pop up window when you go to create the function, but even when I try creating more arguments for the function I get index mismatch errors. An example of a function that can be passed into the app would be very helpful.
(in this example, "signalData" would be ACC_0 from the workspace file)
function afft = ArdupilotFFT(singalData)
Fs = 2000;
L = length(singalData);
L2 = floor(L/2);
f0 = Fs/L*(0:L2-1);
X0 = fft(singalData(:,5));
X0 = 10*log10(abs(X0(1:L2)));
Y0 = fft(singalData(:,6));
Y0 = 10*log10(abs(Y0(1:L2)));
Z0 = fft(singalData(:,7));
Z0 = 10*log10(abs(Z0(1:L2)));
figure(‘Name’,’FFT’);
%subplot(1,3,1);
semilogx(f0,X0,f0,Y0,f0,Z0)
grid on; xlabel(‘Frequency (Hz)’); xlim([1,1000]);
