Detailed Description

4x4 UnMatrix

Author:

Nigel Stewart, RMIT (nigels.com@gmail.com) , Spencer W. Thomas, University of Michigan

Graphics Gems II - Decomposing a matrix into simple transformations. Pg. 320

The unmatrix subroutine fills in a vector of floating point values. These symbols make it easier to get the data back out.
