Re: Gram–Schmidt orthogonalization? |
Hi Jeroen, I was cleaning my mboxes and I stumbled on this mail of yours to pari-users from a looong time ago, which got no answer (sorry): * Jeroen Demeyer [2006-12-11 19:28]: > Does PARI have a function for Gram-Schmidt? I looked around in the help > files, but couldn't find anything. Of course it's easy enough to write > a GP script to do this, but it would be nice to have a native function. We finally have matqr() since February 2013. :-) (It uses Householder reflections rather than Gram-Schmidt, but the end result is the same.)
