 This function sets the number of threads used by some MEX files when compiled
 with OpenMP support (i.e with --enable-openmp is given to configure) or any
 other parallel library.

 INPUTS
  o mexname  [string]    Name of the mex file.
  o n        [integer]   scalar specifying the number of threads to be used.

 OUTPUTS
  none.
