I was reminded by the posts in, New variable programmatically; also: Solving under/over defined system of linear eqautions, that I'd recently used an algorithm for overdetermined systems that I'd unearthed in Wikipedia:  I've documented it's use very simply so that even I'll know how to use it next time it's needed. (memory gets a lot worse with age  ) Perhaps others will find it useful. http://smath.info/wiki/G...LinearEquationSystems.smBrian

The β snippet represents the 'Cholesky' solver, used directly for fitting polynomials to noisy data set. It is also the basic solver in association with the "Conjugate Gradient".  Polynomial fit.sm (51kb) downloaded 28 time(s). Genfit Minimize MODEL [Gauss ERRstem].sm (63kb) downloaded 21 time(s).
