Template arguments

My templated function look as follows:

Code:

template 
void funct(MatTypeOne& m1, MatTypeTwo& m2) {
     //here I would need to check whether m1 and m2 are of the same "type",
     //meaning that MatTypeOne is the same as MatTypeTwo
} 

What is the way to check whether m1 and m2 belong to same/different types?
Thanks
