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 matrix...
