NumericalDerivatives.EvaluateJ Method

NumericalDerivativesEvaluateJ Method

Evaluates the Jacobian for a system of (m) equations in (n) variables.

Namespace: Imsl.Math
Assembly: ImslCS (in ImslCS.dll) Version: 6.5.2.0

Syntax

public double[,] EvaluateJ(
	double[] y
)

Public Function EvaluateJ ( 
	y As Double()
) As Double(,)

public:
array<double,2>^ EvaluateJ(
	array<double>^ y
)

member EvaluateJ : 
        y : float[] -> float[,]

Parameters

y: Type: SystemDouble
A double array of length n, the point at which the Jacobian is to be evaluated.

Return Value

Type: Double
A double matrix containing the Jacobian. Columns that are accumulated must have the additive term defined on entry or else be set to zero. Columns that are skipped can be defined either before or after the EvaluateJ method is invoked.
