Detailed Description

Provides basic functionality for a templated, arbitrarily-sized matrix.

A Matrix is templated to store M rows and N columns of data of type T. If left off, T will default to a "real_t" data type. Also, if N is not specified, the template will default to a square MxM matrix.

Included in this definition are typedefs for the most commonly used matrices (4x4, 3x3, etc), and these can be thought of as shortcuts to reference their associated Matrix templates. For example, Matrix4x4 can be used to refer to Matrix<4, 4, real_t>.

A Matrix stores each of its M rows internally as an N-length Vector called rows which has been defined as:

Vector<N, T> rows[M];
