Is there a function that returns the full path of currently executing compiled program?

This question is for both Unix and Winodws platforms, but more for Unix.

I have a compiled Matlab program that will be deployed to some path. But I don't know what the path will be during coding. Is there a function I can use to return the full path of the executing program when it's deployed and running?

For example, if the program is deployed to /home/folderA, the function will return '/home/folderA/app.exe'.

Will need this capabilities to locate other files in the same path, etc.

Thanks in advance.

Did you try mfilename? Otherwise, here's a snippet I found in my code:

function [thePath] = ShowPath() 
  % Show EXE path: 
  if isdeployed % Stand-alone mode. 
    [status, result] = system('set PATH'); 
    thePath = char(regexpi(result, 'Path=(.*?);', 'tokens', 'once')); 
  else % Running from MATLAB. 
    thePath=pwd; 
  end 
return;

Thanks for your suggestions. The code snippet works on Windows but not on Unix. So I am looking for something equivalent on Unix.

I tried mfilename('fullpath'). On Unix, this returns the path of the MCR cache (e.g. ~/mcrCache7.17/app...) when running in deployed mode.

Look in that folder. Your executable is probably there. As you may or may not know, the exe you installed is not the exe that actually runs - it's really a self unarchiving package that installs the real exe to some secret folder.
