) As Double
public:
static double ConditionNumber(
DoubleComplexTriDiagMatrix^ A
)
static member ConditionNumber :
A : DoubleComplexTriDiagMatrix -> float
Parameters
- A DoubleComplexTriDiagMatrix
- A tridiagonal, Hermitian, positive definite matrix.
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.
