I assume you are talking of rotating a vector or a set of points in a plane or space by 45 degrees.

To achieve this multiply the matrix by

cos(pi/4) sin(pi/4)

-sin(pi/4) cos(pi/4)

Where pi/4 is the radian equiv of 45 degrees. pi = 3.14169

The above method will work for a 2x2 matrix. :) - 06-06-2005xErathQuote:
