Detailed Description
template<class T>
class pdf::matrix_template< T >
The class matrix_template is a template class for two-dimensional matrices.
The representation is based on a valarray with value semantics. This class is designed for matrices of modest size.
The interface is more restricted than for a valarray, e.g. there is no operator+ (const matrix_template<T> & v1, const T & c).
If efficiency becomes an issue, one can defer evaluation and introduce closures (B. Stroustrup, The C++ Programming Language, 3rd edition, 22.4.7)
