Syntax public static float ConditionNumber(
FloatHermitianBandMatrix A,
bool isPositiveDefinite
)
Public Shared Function ConditionNumber (
A As FloatHermitianBandMatrix,
isPositiveDefinite As Boolean
) As Single
public:
static float ConditionNumber(
FloatHermitianBandMatrix^ A,
bool isPositiveDefinite
)
static member ConditionNumber :
A : FloatHermitianBandMatrix *
isPositiveDefinite : bool -> float32
Parameters
- A FloatHermitianBandMatrix
- An Hermitian banded matrix.
- isPositiveDefinite Boolean
- true if A is positive
definite. false otherwise.
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.
