Stable computations with flat radial basis functions using vector-valued rational approximations
Grady B. Wright, Bengt Fornberg
One commonly finds in applications of smooth radial basis functions (RBFs) that scaling the kernels so they are `flat' leads to smaller discretization errors. However, the direct n…

Computing with functions in spherical and polar geometries II. The disk
Heather Wilber, Alex Townsend, Grady Wright
A collection of algorithms is described for numerically computing with smooth functions defined on the unit disk. Low rank approximations to functions in polar geometries are forme…
