This function was created after a discussion in Loren's blog:

Tested: Matlab 2009a/2015b/2018b, Win10, LCC3.8, BCC5.5, OpemWatcom 1.8, MSVC 2008

Compatibility to 64 bit, Linux, MacOS is assumed.

Look in the C-file for instructions to compile the Mex file at first.

A slower M-version is included.
