WitrynaSuppose A = ( 0 1 1 1) has an L U decomposition. Then A = L U for some lower triangular matrix L and upper triangular matrix U. a 11 = l 11 ⋅ u 11 = 0, so it must be either l 11 = 0 or u 11 = 0. Suppose l 11 = 0. Since a 12 = l 11 ⋅ u 12 this would imply a 12 = 0 ≠ 1, a contradiction. Suppose u 11 = 0. WitrynaSIMILAR MATRICES 3 EXAMPLE: 1 1 2 2 is not similar to 1 2 0 1 .
