NMathFunctionsConditionNumber(FloatHermitianBandMatrix) Method

Computes an estimate of the reciprocal of the condition number of a given matrix with respect to the one norm.

Namespace: CenterSpace.NMath.Core
Assembly: NMath (in NMath.dll) Version: 7.4
Syntax
public static float ConditionNumber(
	FloatHermitianBandMatrix A
)

Parameters

A  FloatHermitianBandMatrix
An Hermitian banded matrix.

Return Value

Single
An estimate of the reciprocal of the condition number.
Remarks
The condition number of a matrix A is:
C#
kappa = ||A|| ||AInv||
where AInv is the inverse of the matrix A. This function returns an estimate of the reciprocal of the condition number, rho = 1/kappa.
