Radial basis function interpolation

Radial Basis Function (RBF) interpolation is a method used in numerical analysis and computational mathematics to interpolate scattered data points in multidimensional space. It is particularly effective for problems where the data is irregularly spaced, as it can approximate values at unmeasured points based on the values of known points. ### Key Concepts: 1. **Radial Basis Function**: An RBF is a real-valued function whose value depends only on the distance from a center point.
