AB = -BA matrices viewer

This toy demo program visualize 2x2 matrix pairs A and B, they satisfy AB = -BA.

AB_MBA_SHOW visualize 2x2 matrices A and B, they satisfy AB = -BA.

You can fin this problem in Introduction to Linear Algebra 4th ed. by
Gilbert Strang. Chapter 2, Section 4, Rules for Matrix Operations,
p.78, Problem 22.

This visualiser contains all the AB = -BA, A and B are 2x2 matrix with the case of elements are only {-1, 0, 1}.
The matrix pairs are generated by find_ab_mba.m (other my post.)
