| NMathFunctionsEstimateConditionNumber(FloatMatrix, NormType) Method |
Estimates the reciprocal of the condition number of a given matrix
in the specified norm type.
Namespace: CenterSpace.NMath.CoreAssembly: NMath (in NMath.dll) Version: 7.4
Syntax public static float EstimateConditionNumber(
FloatMatrix A,
NormType norm
)
Public Shared Function EstimateConditionNumber (
A As FloatMatrix,
norm As NormType
) As Single
public:
static float EstimateConditionNumber(
FloatMatrix^ A,
NormType norm
)
static member EstimateConditionNumber :
A : FloatMatrix *
norm : NormType -> float32
Parameters
- A FloatMatrix
- A matrix.
- norm NormType
- The norm used to compute the condition number.
Return Value
SingleAn estimate of the reciprocal of the condition number of
the matrix
A.
Exceptions Remarks
The condition number of
A is:
where
AInv is the inverse of the matrix
A.
This function returns an estimate for
rho = 1/kappa
which is never less than
rho and in practice is nearly always less than
10*rho.
