Radial basis functions (RBFs) have become a popular method for interpolation and solution of partial differential equations (PDEs). Many types of RBFs used in these problems contain …
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 numerical …
