WebJul 3, 2013 · A = matrix ( [ [1,2,3], [11,12,13], [21,22,23]]) By definition, the inverse of A when multiplied by the matrix A itself must give a unit matrix. The A chosen in the much praised explanation does not do that. In fact just looking at the inverse gives a clue that the inversion did not work correctly. WebNo, if you multiply by a matrix filled with 1's, you get a new matrix of values. Say you have a 3 x 3 matrix of values [ 2 -2 4 ] 1 3 9 [-4 8 .5 ] If you multiply by a 3 x 3 matrix of 1's your result (product) is [ 4 4 4 ] 13 13 13 [4.5 4.5 4.5 ]
