Hi, What is the best way to solve a system of positive-definite linear equationsusing smath( as used in structural analysis of space frames)? Elsewhere I have used software that makes use of public domain solver libraries for this. Can these be adapted for use in Smath? Thanks farlanw Edited by user 11 October 2012 12:48:35(UTC)

Iterative methods are faster than direct for large systems, for positive definite linear matrices I've read here that PCG ( "preconditioned conjugate gradient method" ) is quite efficient in general. WikipediaAlgorithm pseudocodeEdited by user 07 October 2012 04:34:34(UTC)
