Multiply a 3D matrix

Multiply a 3D matrix
 1# This example multiplies two 3D matrices
 2# and prints the result to output screen
 3
 4# Create a local variable for the impact.creator ThreeD object
 5three_d  = impact.creator.three_d()
 6
 7# Create a default 3D matrix (Identity matrix)
 8matrix1 = three_d.matrix3_d()
 9
10# Create another default 3D matrix (Identity matrix)
11matrix2 = three_d.matrix3_d()
12
13# Multiply with existing matrix
14call(matrix1.multiply(matrix2))
15
16# Create a local variable for the output toolbox
17ot = impact.gui.output_toolbox
18
19# Print the matrix to output toolbox
20ot.add(matrix1.to_string())
