Here, we simply compute C = A * B. Because B is inverse ( A ), C should be the identity. Matrix A: Col: 1 2 3 Row --- 1: 1.00 1.00 2.00 2.00 10.0 2: 1.00 1.00 0.00 3.00 -5.00 14.0 3: 1.00 1.00 0.00 5.00 -8.00 20.0 Matrix B: Col: 1 2 3 Row --- 1: 10.0 1.00 -2.00 6.00 -3.00 -2.00 2: 9.00 -3.00 0.00 8.00 -3.00 -2.00 3: -2.00 2.00 -1.00 -2.00 1.00 Product C = A * B: Col: 1 2 3 Row --- 1: 1.00 0.00 0.00 2: 0.00 1.00 0.00 3: 0.00 0.00 1.00 BLAS3_Z_PRB Normal end of execution. 03 April 2014 1:19:22.989 PM
