Computes an estimate of the reciprocal of the condition number of a given matrix in the specified norm type.

Namespace:  CenterSpace.NMath.Matrix
Assembly:  NMath (in NMath.dll) Version: 5.1.0.0

Syntax

C#
public double ConditionNumber(
	NormType norm
)
Visual Basic (Declaration)
Public Function ConditionNumber ( _
	norm As NormType _
) As Double
Visual C++
public:
double ConditionNumber(
	NormType norm
)

Parameters

norm
Type: CenterSpace.NMath.Core..::.NormType
The norm used to compute the condition number.

Return Value

An estimate of the reciprocal of the condition number.

Remarks

The condition number of a matrix A is:
CopyC#
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.
