with respect to the one norm.
Namespace: CenterSpace.NMath.CoreAssembly: NMath (in NMath.dll) Version: 7.4
Syntax public static float ConditionNumber(
FloatUpperTriMatrix A
)
Public Shared Function ConditionNumber (
A As FloatUpperTriMatrix
) As Single
public:
static float ConditionNumber(
FloatUpperTriMatrix^ A
)
static member ConditionNumber :
A : FloatUpperTriMatrix -> float32
Parameters
- A FloatUpperTriMatrix
- A upper triangular matrix.
Return Value
SingleAn 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.
