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

Namespace: CenterSpace.NMath.Matrix
Assembly: NMathPremium (in NMathPremium.dll) Version: 5.3.0.0

Syntax

C#
public static float ConditionNumber(
	FloatComplexBandMatrix A,
	NormType norm
)
Visual Basic
Public Shared Function ConditionNumber ( _
	A As FloatComplexBandMatrix, _
	norm As NormType _
) As Single
Visual C++
public:
static float ConditionNumber(
	FloatComplexBandMatrix^ A, 
	NormType norm
)

Parameters

A
Type: CenterSpace.NMath.Matrix..::..FloatComplexBandMatrix
A banded matrix.
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:
 Copy imageCopy
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.
