is there a sort of configurartion for mex on a matlab function block?

I have been struggling to build a mex file from a MATLAB function block. I have visual studio 2012 and MATLAB R2013a installed but it always can't locate the compiler. I have tried going to mex-setup from the command window but it just gives a text usage Mex[option 1..option n]source file1....., a path to mex.pl located in d MATLAB folder and an error: undefined function or variable 'setup'

Make sure you use

mex -setup

with a space between "mex" and "setup". Otherwise it is going to think that you are trying to do a subtraction.
