matRad_checkMexFileExists(filename, linkOctave)

Checks if a matching mex file exists, and can create a link if a matching custom, system specific precompiled octave mex file is found

call

Input:

If false, the function will only check for an existing .mex file for octave.

Output:

fileExists – true if the mex file exists (or can be linked), and false otherwise
