Create a square, almost symmetric 4 X 4 matrix B with values 1,
2, 3 and 4 on the diagonal. Let values off diagonal be between 0.01
and 0.2. Almost symmetric matrix is not a scientific term. It just
means that most of the off diagonal terms on transpose positions
are close in value:
1. Determine matrix BINV which is an inverse of matrix B;
2. Demonstrate that the matrix multiplied by its inverse
produces a unit matrix. Unit
