What are 'Good' Points for Local Interpolation by Radial Basis Functions?

Radial basis function interpolation has an advantage over other methods in that the interpolation matrix is nonsingular under very weak conditions on the location of the interpolation points. However, we show that point location can have a significant effect on the performance of an approximation in...
