WebThe RBF class, which is used to evaluate RBFs and their exact derivatives; The RBFInterpolant class, which is used to interpolate scattered and potentially noisy N-dimensional data. One can also evaluate the exact derivatives of the interpolant; The weight_matrix function In applied mathematics, polyharmonic splines are used for function approximation and data interpolation. They are very useful for interpolating and fitting scattered data in many dimensions. Special cases include thin plate splines and natural cubic splines in one dimension.
