Hi, backsolve() is probably what you are looking for. Martyn -Original Message- From: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] On Behalf Of Michael Meyer Sent: 03 December 2013 12:25 To: r-help@r-project.org Subject: [R] triangular matrix inverse Greetings

[R] triangular matrix inverse

2013-12-03 Thread Michael Meyer

Greetings, is there an algorithm which computes the inverse of a triangular matrix while being aware of its triangular form? I know about solve() but this is probably not efficient on a triangular matrix. Thanks, Michael Meyer [[alternative HTML version deleted]] ___
