Implemented radial basis functions (RBFs) for surface spline interpolation. More...

Detailed Description

The symbols used in the following table are:

phi(r) The radial basis function evaluated at a point (x,y) r Distance to center, r^2 = (x-xc)^2 + (y-yc)^2 (xc,yc) Center point eps Shape parameter

RadialBasisFunction::Unknown Unknown or unsupported function.
RadialBasisFunction::VariableOrder phi(r) = (r^2)^(m-1) * Ln( r^2 )
RadialBasisFunction::ThinPlateSpline phi(r) = r^2 * Ln( r )
RadialBasisFunction::Gaussian phi(r) = Exp( -(eps*r)^2 )
RadialBasisFunction::Multiquadric phi(r) = Sqrt( 1 + (eps*r)^2 )
RadialBasisFunction::InverseMultiquadric phi(r) = 1/Sqrt( 1 + (eps*r)^2 )
RadialBasisFunction::InverseQuadratic phi(r) = 1/( 1 + (eps*r)^2 )
