Output a 3D matrix

Output a 3D matrix
 1# This example prints a 3D matrix to output screen
 2
 3# Create a local variable for the impact.creator ThreeD object
 4three_d  = impact.creator.three_d()
 5
 6# Create a default 3D matrix (Identity matrix)
 7matrix = three_d.matrix3_d()
 8
 9# Create a local variable for the output toolbox
10ot = impact.gui.output_toolbox
11
12# Print the matrix to output toolbox
13ot.add(matrix.to_string())
