GPCMT3 - Compose Matrix 3

GPCMT3 (matra, matrb, matrix)

Purpose

Use GPCMT3 to perform a 44 matrix multiplication and return the results.

Transformation Matrix A (matra) Transformation Matrix B (matrb) is computed and returned in matrix

For this task, the elements of the transformation matrixes are passed in the following order:

                 
  |m11 m12 m13 m14|
  |m21 m22 m23 m24|---> (m11,m12,m13,m14,m21,m22,...m44)
  |m31 m32 m33 m34|
  |m41 m42 m43 m44|

Parameters

matra -- specified by user, 16 short floating-point numbers

Transformation matrix A.

matrb -- specified by user, 16 short floating-point numbers

Transformation matrix B.

matrix -- returned by the graPHIGS API, 16 short floating-point numbers
