Summary
A Represents a 3×3 matrix that represents an affine transformation.
Description
A TGPMatrix object represents a 3×3 matrix that, in turn, represents an affine transformation. A Matrix object stores only six of the 9 numbers in a 3×3 matrix because all 3×3 matrices that represent affine transformations have the same third column (0, 0, 1).
