RadialBasisFunctions.InverseMultiquadric Method

public static RadialBasisFunction InverseMultiquadric(
	double shape
)

Public Shared Function InverseMultiquadric ( 
	shape As Double
) As RadialBasisFunction

public:
static RadialBasisFunction^ InverseMultiquadric(
	double shape
)

static member InverseMultiquadric : 
        shape : float -> RadialBasisFunction 

Parameters

shape  Double

The shape parameter ε that controls the width of the kernel. Must be positive.

Return Value

The inverse multiquadric kernel produces smooth interpolants that decay to zero as r increases. It is a conditionally positive definite kernel. The shape parameter ε controls the width of the basis functions.

The kernel is defined as φ(r) = 1/√(1 + (εr)²) where ε is the shape parameter and r is the radius.
