public class PMatrix2D extends java.lang.Object implements PMatrix
PMatrix for a
general description. This matrix looks like the following when multiplying
a vector (x, y) in mult().
[m00 m01 m02][x] [m00*x + m01*y + m02*1] [x'] [m10 m11 m12][y] = [m10*x + m11*y + m12*1] = [y'] [ 0 0 1 ][1] [ 0*x + 0*y + 1*1 ] [ 1](x', y') is returned. The values in the matrix determine the transformation. They are modified by the various transformation functions.
