Perusing the sci.math.num-analysis Usenet archives, I came across this post by G. W. Stewart on comparing Cramer's rule and Gaussian elimination for solving linear equations. I decided to write a TI-BASIC program similar to the Matlab code he posted there, and thus bore out the same conclusions.
As is often said for solving linear equations (especially ill-conditioned ones), what to do depends on whether you want accurate solutions (solution has as many correct digits as possible) or small residuals (solution satisfies the given equations)

P.S. This is more expository than practical, so I post the program here instead of in the TI-BASIC forum. |
