How to invoke square_me fundtion


I’m starting to learn CUDA with Matlab. I have installed and everything is working.
So to start to understand CUDA, I started with the function given in the “Acceleration Matlab with CUDA” paper.
It compiled fine in to a .mexglx file and now the problem is how to invoke the function.
I cannot understand what the input arguments should be? the function is returning nothing.

Can anybody give me a hint as what to put in the argument list square_me(float*, float*, int) ?

Thank you.
