Back Substitution - an overview ScienceDirect Topics

A matrix equation in the form or is very easy to solve by an iterative process called forward substitution for lower triangular matrices and analogously back substitution for upper triangular matrices. The process is so called because for lower triangular matrices, one first computes , then substitutes that forward into the next equation to solve for , and repeats through to . In an upper triangular matrix, one works backwards, first computing , then substituting that back into the prev… 웹Backward substitution: solve U x = y . 不过我们的前两步比较隐式和同时进行。. 解决的办法就是行交换，把比较大的pivot放在前面。. 其实这个我们手动解 A\mathbf {x} = \mathbf {b} 的时候就会这样做，英文叫做 Gaussian elimination with partial pivoting (GEPP). 这个英文就暗示了还 …
