3.3 Radial basis function interpolation 3.3.1 Radial basis functions Definition 3.3.1. A function ϕ: ℝn→ℝ is called radial function centered at the origin provided it is a univariate function in terms of variable r, so we have this: (3.26)ϕ(x)=ϕ(r),x∈ℝn where the re...
TheRadialBasisFunctionInterpolationcommand creates a functionfx1,...,xn=valuewhich can then be evaluated at arbitrary points inRn. • The supported radial basis functions aregaussian,inversequadratic,multiquadric,inversemultiquadric,linear,cubic, andthinplatespline. The default ismultiquadr...
