more templates at once?

[carnaz]

I'm really unexperienced, so maybe it's nonsense. But I would like to know whether is there a possibility to use many different templates in one method or operator like:

template < class T, int x, int y> class CMatrix
{
// blah blah blah...
}

template < class T, int x, int z>
template < class T, int y, int z>

CMatrix < T, x, z> CMatrix< T, x, y> :: operator * ( CMatrix < T, y, z> m)
{
CMatrix < T, x, z> r;
// blah blah blah
return r;
}

I know, syntax is not correct, template keyword shouldn't be used like above, but if You know how to handle this problem I appreciate any advice.
