SpletAny other LU-decomp would be of the form: A = L U = L I n U = L D D − 1 U = ( L D) ( D − 1 U) with D ∈ R n × n, D ≠ I n. For this ( L D) ( D − 1 U) to be a LU-decomposition, we need L D lower triangular, ( D − 1 U) upper triangular. In order for L D to stay a lower triangular matrix, D needs to be lower triangular. coffee mate 250g priceSplet6.1.3 Solution of linear systems using LU decomposition We can make use of the LU factorisation of A to solve the linear system Ax = LUx = b in a two-step triangular process.
