Detailed Description

template<class T>
class mat::MatrixInterface< T >

Abstract base class providing a simple unified virtual-function interface to matrices of various types.

Normally, functions are written to handle different matrix types by accepting a template parameter for the matrix type. Sometimes, however, e.g. when keeping a list of matrices of different types, one needs to have run-time polymorphism instead of just compile-time polymorphism. If such a list uses this base class as its element type, any compatible matrix may be wrapped with one of the classes below so that it can be stored on the list. The main requirement is that the value_type of each matrix be the same.

Of course, since this interface relies on virtual functions, it will be somewhat slower than accepting a template parameter.
