Detailed Description

template<class RBFKernel, class PolyTail>
class sot::RBFInterpolantCap< RBFKernel, PolyTail >

Capped RBF interpolant.

This is a capped version of the RBF interpolant that is useful in cases where there are large function values. This version replaces all of the function values that are above the median of the function values by the value of the median.

Template Parameters

RBFKernel	Radial kernel (Cubic is default)
PolyTail	Polynomial tail (Linear is default)
