WebA variant on RBF interpolation is normalized radial basis function (NRBF) interpolation, in which we require the sum of the basis functions to be unity. NRBF arises more naturally from a Bayesian statistical perspective. However, there is no evidence that either the NRBF method is consistently superior to the RBF method, or vice versa. WebRbf is legacy code, for new usage please use RBFInterpolator instead. x, y, z, …, d, where x, y, z, … are the coordinates of the nodes and d is the array of values at the nodes. The radial …
