NR::Matrix Class Reference

#include <nr-matrix.h>

List of all members.

Detailed Description

The Matrix class.

For purposes of multiplication, points should be thought of as row vectors

p = ( p[X] p[Y] 1 )

to be right-multiplied by transformation matrices

    c[] = | c[0] c[1]  0  |
          | c[2] c[3]  0  |
          | c[4] c[5]  1  |                           

(so the columns of the matrix correspond to the columns (elements) of the result, and the rows of the matrix correspond to columns (elements) of the "input").
