Namespace: Imsl.MathAssembly: ImslCS (in ImslCS.dll) Version: 6.5.2.0
Syntax public double PerformanceIndex(
double[,] a
)
Public Function PerformanceIndex (
a As Double(,)
) As Double
public:
double PerformanceIndex(
array<double,2>^ a
)
member PerformanceIndex :
a : float[,] -> float
Parameters
- a
- Type: SystemDouble
A double symmetric matrix.
Return Value
Type:
Double
A
double scalar value indicating how well the algorithms which
have computed the eigenvalue and eigenvector pairs have performed.
Remarks
A performance index less than 1 is considered excellent, 1 to 100 is
good, while greater than 100 is considered poor.
