Detailed Description

template<class T, std::size_t NRows, std::size_t NCols>
class tvmet::Matrix< T, NRows, NCols >

A tiny matrix class.

The array syntax A[j][j] isn't supported here. The reason is that operator[] always takes exactly one parameter, but operator() can take any number of parameters (in the case of a rectangular matrix, two paramters are needed). Therefore the cleanest way to do it is with operator() rather than with operator[].
