with respect to the specified norm.
Namespace: CenterSpace.NMath.CoreAssembly: NMath (in NMath.dll) Version: 7.4
Syntax public static double ConditionNumber(
DoubleComplexUpperTriMatrix A,
NormType norm
)
Public Shared Function ConditionNumber (
A As DoubleComplexUpperTriMatrix,
norm As NormType
) As Double
public:
static double ConditionNumber(
DoubleComplexUpperTriMatrix^ A,
NormType norm
)
static member ConditionNumber :
A : DoubleComplexUpperTriMatrix *
norm : NormType -> float
Parameters
- A DoubleComplexUpperTriMatrix
- A upper triangular matrix.
- norm NormType
- The norm used to compute the condition number.
Return Value
DoubleAn estimate of the reciprocal of the condition number.
Remarks
The condition number of a matrix
A is:
where
AInv is the inverse of the matrix
A. This function
returns an estimate of the reciprocal of the condition number,
rho = 1/kappa.
