Syntax public static float ConditionNumber(
FloatComplexTriDiagMatrix A,
bool isHermitianPD
)
Public Shared Function ConditionNumber (
A As FloatComplexTriDiagMatrix,
isHermitianPD As Boolean
) As Single
public:
static float ConditionNumber(
FloatComplexTriDiagMatrix^ A,
bool isHermitianPD
)
static member ConditionNumber :
A : FloatComplexTriDiagMatrix *
isHermitianPD : bool -> float32
Parameters
- A FloatComplexTriDiagMatrix
- A tridiagonal, Hermitian, positive definite matrix.
- isHermitianPD Boolean
- true if A is Hermitian and positive definite.
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.
