The most I have is: A Mathematica package to interpolate data with Radial Functions

Roberto Ferretti

Is there any special reason to use RBF? It does not seem a particularly efficient strategy: you have to solve a large, strongly coupled nonlinear system by computing all the values of the approximate solution at the same time.

Mathematica has more efficient solvers for ODE.
