Hi,

I guess this is related to http://www.mathworks.com/matlabcentral/answers/13952-convert-c-code-to-matlab-mex-file?

You probably get a more specific help when asking more specific questions...

you create a mexFunction in which you tell matlab how many outputs and inputs and you read your inputs and define your outputs. I think this link can help you

http://www.mathworks.com/help/techdoc/matlab_external/f12977.html

The truth is you need to play with it, in that page there are very simple but meaningful examples. It also points you to build in examples inside matlab.

If you use Matlab this example is very ilustrative
