I decided to use MatLab to play with polynomial fitting (and it also has built-in polynomial fitting routines for comparison ! See polyfit and polysolve .) Since MatLab has the brain dead requirement of one function per file, this resulted in a handful of files :

• Top Level workpage
• Function being fitted
• Polynomial fitting routine
• Solve using polynomial eqn.
• Radial Basis Function fitting routine
• Solve using RBF eqn.
