These commands are all from within Matlab. They demonstrate that Matlab (or GNU Octave) MEX C / C++ compiler wrapper is working on your system.

1. Using the Matlab example to your home directory with homepath.m

   copyfile(fullfile(matlabroot,'extern','examples','mex','yprime.c'), homepath)

   1. in Matlab or GNU Octave compile the callable C-code by:

   mex([homepath,filesep,'yprime.c'])

2. use the compiled C-code function from Matlab or Octave by:

   yprime(3,[4,2,7,1])

   which returns

   ans = 2.0000 5.9924 1.0000 2.986

   Fix

   if you get missing compiler errors, do Mex setup
