Also, made a custom function named CheckLowerTriangularMatrix () to … WebFor example, if you have a lower-triangular matrix L, and you see an expression like L − 1 y, you should almost never actually compute L − 1 and then multiply it by y. Instead, you would solve L x = y by forward-substitution, obtaining x = L − 1 y.

WebLower Triangular Matrix An n × n square matrix A = [a ij] is said to be a lower triangular matrix if and only if a ij = 0, for all i < j. This implies that all elements above the main diagonal of a square matrix are zero in a lower triangular matrix. A general notation of a lower triangular matrix is L = [l ij for i ≥ j, 0 for i < j].
