Undefined function ‘syms’ for input arguments of type ‘char’, what can I do?
In matlabR2023b, I packaged two m files into an exe file, in need of solving equations, I used the function ‘syms’ in these two m files. There was no problem running these m files before. However, running the generated exe file report errors. The error code is as follows. What is the reason for this? What should I do? Could you please give me some advice? Thank you!
Error code: Undefined function ‘syms’ for input arguments of type ‘char’.
‘syms’ was excluded from packaging for the MATLAB Runtime environment according to the MATLAB compiler license. Have the application owner either resolve the file or function from the code, or use the MATLAB function "isdeployed" to ensure the function is not invoked in the deployed component.
Connect the application owner for more details.

sub-libraries don’t appear in teh Simulink Browser
Hi there,
I’ve several simulink sub-libraries with the slblocks.m file defined as follows:
Browser.Library = ‘library_name’;
Browser.Name = ‘library name’;
Browser.IsTopLevel = 0;
Apart from that, I’ve a master library from which I call the rest of sub-libraries using the OpenFcn callback. slblock.m file for this master library is defined as:
Browser.Library = ‘library_name’;
Browser.Name = ‘library name’;
Browser.IsTopLevel = 1;
Everything seems to be ok because I can see the master libary and sub-libraries in the browser. However, containing blocks of each sub-library are not shown in the right part of the browser. I need to open the library and save it (without any change). After this, the beneath blocks are shown.
Any clue? Thanks in advanced,

Sateflow: Indexing an array of size 1
Hi,
I need to index an array that can be of size 1 to x. Indexing in gerneral is no issue, as long as the size of the array is >1 (e.g. using A[x]). But as soon as the array size is 1 I get the following error for a transition check:
[i == 0 && A[i] >= B[i]]
Array dimension mismatch for data A.
Size of a is defined empty.
Anyone an idea for a generic approach?

Three-Phase V-I Measurement with 4 wires
There’s a block from the Simscape library called Three-Phase V-I Measurement (picture attached). I would like to use it with a three-phase system that has 4 wires (ABCN, 3 phases and 1 neutral). How should I go about this?
I suppose the best way is to create a custom block. I was reading this documentation, but I was wondering if there’s some type of S-function written for the block that alredy exists so I can understand how it works better and I write my own code for my modified block.There’s a block from the Simscape library called Three-Phase V-I Measurement (picture attached).

How capture the error value for each epoch?
Hello, everyone!
I’m having a problem regarding my college project and I would like to know how I could obtain the RMSE value at each epoch of my model’s execution, and export in a .xlsx archive.
rmseValues = zeros(numEpochs, 1);
for epoch = 1:numEpochs
[net, info] = trainNetwork(XTrain, YTrain, layers, options);
YPred = predict(net, XTrain);
rmseValues(epoch) = calculateRMSE(YTrain, YPred);
end
rmseTable = array2table(rmseValues, ‘VariableNames’, {‘RMSE’});
disp(rmseTable);
However, due to the nature of the for loop, training is performed at the same rate as the number of epochs defined. I would therefore like to know if there is a function that allows me, for example, to obtain the array of execution data.
The motivation is that I would like to use this data for another project.Hello, everyone!

How to fix MATLABWindow application failed to launch
I have just finished doing a fresh install of MATLAB R2024a on a Ubuntu 22.04 based operating system, and have replicated the problem with R2023b. To begin, the install script would fail with the following error:
terminate called after throwing an instance of ‘std::runtime_error’
what(): Failed to launch web window with error: Unable to launch the MATLABWindow application. The exit code was:
1
Aborted
I was able to rectify this issue by appending the following line to the install script before the final line:
export LD_PRELOAD="/usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.30"
Now that I have installed MATLAB, the issue nonetheless persists. When I try to open the add on window, I get the error:
Error using matlab.internal.cef.webwindow (line 403)
MATLABWindow application failed to launch. Unable to launch the MATLABWindow application. The exit code was: 1
I have tried the instructions listed here

but I have had no luck.
Update: MATLAB is completely broken, and I cannot open any files. I am met with the following error:
Unable to open this file in the current system configuration. For more information, see Requirements.
For now, I will be reverting back to a previous system snapshot, as I have wasted enough time trying to fix this issue.I have just finished doing a fresh install of MATLAB R2024a on a Ubuntu 22.04 based operating system, and have replicated the problem with R2023b.

Why ILP Solver Switching to Branch-and-Bound?
Hello everyone,
I’m working on an integer linear programming (ILP) problem in MATLAB. When I solve the problem with a small number of variables, the solver quickly finds an optimal solution. However, when I increase the number of variables, the solver uses the branch-and-bound algorithm, which takes a long time. I would like to know if the ILP will display an optimal solution after the iterations of the branch-and-bound algorithm?
Any insights or tips on why the solver switches to branch-and-bound would be greatly appreciated!

matlab 2017b command windpow opens but does not open up editor window. MATLAB_Editor_State.xml shows the expected files that should be open in editor
command window opens but in the default configuration, not the last one I used
editor windows that had a multitude of tabs open to various scripts and guide programs does not open at all
If I try to open a matlab script (xxx.m) I get a new command window opening and an editor window with the xxx.m file in a separate window
the file MATLAB_Editor_State.xml still holds the data on each of the matlab scripts I expect tot be open in the editor.
so it looks like matalb cannot find the proper configuration to open up properly how do I fix this ?
