As far as I know, by using mldivide, MATLAB will use LU decomposition as my matrix A doens't have any specific property except for being square. My question : So I'm wondering if I'd gain some time by first decomposing A using MATLAB's lu , and then feed these to linsolve in order to solve x = U\(L\b) with opts being respectively upper and lower triangular.

Alternatively, to use the parameters in the MATLAB workspace use syms to This is MATLAB implementation for LU decomposition, forward substitution, backward substitution, and linear system solver. The functions written are: nma_LU.m.txtLU decomposition with partial pivoting with threshold support. Description The lufunction expresses a matrix Xas the product of two essentially triangular matrices, one of them a permutation of a lower triangular matrix and the other an upper triangular matrix. The factorization is often called the LU, or sometimes the LR, factorization. decomposition creates reusable matrix decompositions (LU, LDL, Cholesky, QR, and more) that enable you to solve linear systems (Ax = b or xA = b) more efficiently.
