PROGRAM 4: Behavior of matrix composition

CHARACTERISTICS: nnnn

OPERATOR SCRIPT: passive test.

DESIGN:

TEST: #SR 1 2 11
      "The matrix returned by <compose matrix 3> should perform
       the same 3D transformation as that resulting from the
       multiplication of the two specified matrices."

Initialize array A4 to: | -2.2       3.3   4.4   5.5   |
                        |  0.0023 -727.12  2.09 33.33  |
                        |  0        34    54.1  -0.045 |
                        |  7         6     5     4     |

Initialize array B4:
inc = 0
do i=1,4
do j=1,4
  b(i,j) = tan(-1.56 + inc)
  inc = inc + 3.0/16.0
next j
next i

<Compose matrix 3> using A4 and B4 returns act4x4 = actual array
Compute exp4x4 = expected array
pass/fail depending on (act4x4 represents same transformation as exp4x4)

TEST: #SR 1 2 12
      "The matrix returned by <compose matrix> should perform
       the same 2D transformation as that resulting from the
       multiplication of the two specified matrices."

Initialize array A3 to: | -2.2       3.3    5.5   |
                        |  0.0023 -727.12  33.33  |
                        |  0        34     -0.045 |

Initialize array B3:
inc = 0
do i=1,3
do j=1,3
  b(i,j) = tan(-1.56 + inc)
  inc = inc + 3.0/9.0
next j
next i

<Compose matrix> using A3 and B3 returns act3x3 = actual array
Compute exp3x3 = expected array
pass/fail depending on (act3x3 represents same transformation as exp3x3)
