MATLAB: Generic error by MATLAB Coder

matlab coder

I am trying to use the MATLAB Coder app to compile a MATLAB function into C code, but I get the following generic error:

"Generation of trial code failed"

When I press the view errors button, nothing is showed.

When I use the "codegen" command for just code generation (without any sort of compiling), I get the following error:

??? CODEGEN requires a MATLAB Coder license.

I have a floating network license. How do I resolve this?

The issue occurs because of the unavailability of license. However, the Coder app is supposed to warn you about the unavailability of the license. This lack of warning is a known bug and has been fixed for R2017b. For now, you can use the following command as a workaround to ascertain that you have the MATLAB Coder license available before proceeding to the Coder app:

>> license('checkout','MATLAB_Coder')

MATLAB: Do I receive an error message of “mclmcr.dll not found” while deploying the application on a target machine using the ‘MCRInstaller.exe’ in MATLAB 7.0.4 (R14SP2)

This behavior is observed in MATLAB due to a corrupt installation of the MCR.

To work around this issue, add the <mcrroot>\v72\bin\win32 folder to the system path, where mcrroot corresponds to the directory into which the MCR is installed. However, this may cause problems with other versions of MCR since the file 'mclmcrrt72.dll', which calls the 'mclmcr.dll', is version specific.

Hence, the other option is to reinstall the MCR using 'MCRInstaller' on the target machine.

You can find the 'MCRInstaller.exe' in the following directory:

$MATLAB\toolbox\compiler\deploy\win32

(where $MATLAB is the MATLAB root directory as returned by the following command:

matlabroot

)

MATLAB: Does the app freeze when loading data to a Table in App Designer and MATLAB R2017b

This issue does not occur in MATLAB R2018a.

To workaround this issue in MATLAB R2017b, add some "pause" statements:

>> app.StartButton.UserData='stopped';
>> pause(1);
>> view(app.AnimAxes, 30,2)
>> pause(1);
>>
>> LoadData(app);
>> pause(1);
>> app.Brake_Table.Data(:,1) = app.Data11;
>> app.Brake_Table.Data(:,2) = app.Data12;
>> pause(1);
>> app.Brake_Table_2.Data(:,1) = app.Data21;
>> app.Brake_Table_2.Data(:,2) = app.Data22;
>> pause(1);
>>
>> app.ax_Carposplot.XLim = [0 10];
>> app.ax_Carvplot.XLim = [0 10];
>> app.ax_Caraplot.XLim = [0 10];
>> app.ax_SCplot.XLim = [0 10];
>> app.ax_SCplot.YLim = [-0.2 1.2];
>> app.ax_SCplot.YTick = [0 1];
>> app.ax_SCplot.YTickLabel = {'open', 'closed'};
