Detailed Description

Matrix used in linear algebra.

This class implements the concept of Matrix as used in linear algebra. As such, it is not meant to be used as a container.

Member Function Documentation

const Matrix & operator+= (const Matrix & m)


all matrices involved in an algebraic expression must have the same size.
