1. Solve the lower triangular system Ly = b for y by forward substitution. 2. Solve the upper triangular system Ux = y for x by back substitution. Moreover, consider the problem AX = B (i.e., many different right-hand sides that are associated with the same system matrix). In this case we need to compute the factorization A = LU only once, and

Complexity of LU Decomposition to solve Ax=b: – decompose A into LU-- cost 2n3/3 flops – solve Ly=b for y by forw. substitution -- cost n2 flops – 2solve Ux=y for x by back substitution -- cost n flops slower alternative: – -1compute A-- cost 2n3 flops – multiply x=A-1b-- cost 2n2 flops this costs about 3 times as much as LU 2021-01-05 · Time Complexity: Time Complexity is a way of representing or to get to know how the run-time of a function increases/decreases as the size of the input increases/decreases. There are many types of time complexity for example: Linear Time —-> Already discussed in the above scenario where we helped my cousin from being embarrassed in front of LU factorization every nonsingular matrix A can be factored as A =PLU with P a permutation matrix, L lower triangular, U upper triangular cost: (2/3)n3 flops SolvinglinearequationsbyLUfactorization. given a set of linear equations Ax =b, with A nonsingular.
