How to add user created .mat files to the search path after compilation

Question

How can I allow user to add additional dependenies after the source code was compiled with mcc.

I was thinking about an empty folder next to the executable, where the users can add the needed .mat-files, but I can't add the folder path to my executable (since addpath is not allowed in deployed applications).

Any ideas?

This answer assumes that your code can be customised by data contained in one or more .mat files at runtime.

You can point your code to look at a folder where the optional .mat file(s) would be located.

For example in the users home folder with a sub folder being the name of your application (or in the local app data) or whereever...

If you want it in a sub folder where the exe is, you can do this as well, you find the exe path using (on windows):

[status, result] = system('path');
installpath = char(regexpi(result, 'Path=(.*?);', 'tokens', 'once'));
fprintf ( 'The exe install path is "%s"\n', installpath );

Then your code looks to load for example:

file2load = fullfile ( installpath, 'subFolder', 'runtimeCustomisation.mat' )
if exist ( file2load, 'file' ) == 2
  "doSomething with the file"
end

Or something like that.

Recall that this is for dependencies which are .mat files only.
