This small script computes the compact support radial basis functions due to Holger Wendland. The computation is iterative, based on repeated symbolic integration, with the output being a function handle that is cheaply called. The original reference for these functions is Wendland, H. (1995) Piecewise polynomial, positive definite and compactly supported radial functions of minimal degree. Advances in Computational Mathematics 4(1), 389-396.

2.0.0.0

This version fixes a bug to ensure that the Wendland RBFs are 0 on (-inf,0] and [1,inf), whereas before they took the value 1/2 at 0, due to how the Heaviside function is defined in MATLAB.
