Best Answer

The mex command does not perform magic tricks, it simply starts the compiler. Unfortunately mex has grown to a very obfuscated piece of code since Matlab 4. It are some M-, Perl- and BAT-files, while the last are not executed, but parsed by teh Perl functions.
If you find out the parameters used for starting the compiler, you can start the compiler by a single system call also.
