Hi,

the following code works:

template < class M >
void printDimensions(const matrix_expression<M>& m){
   cout << (m()).size1() << "x" << (m()).size2() << endl;
}

Note the extra () around m(). This makes all the difference.

However, this is not what I want. I want to be sure that a matrix of
double is passed, but that matrix can be of arbitrary type (sparse /
dense). How can I achieve that?

Thanks for all your replies!

Markus
