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 ] WebInstead, you would solve L x = y by forward-substitution, obtaining x = L − 1 y. More quantitatively, if you have an m × m upper/lower triangular matrix T, then you can solve T x = y by back/forward-substitution in Θ ( m 2) operations, whereas computing T − 1 for a general triangular matrix requires Θ ( m 3) operations.
