NumericalDerivatives.IJacobian.Jacobian Method

NumericalDerivativesIJacobianJacobian Method

User-supplied function to compute the Jacobian.

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

Syntax

double[,] Jacobian(
	double[] y
)

Function Jacobian ( 
	y As Double()
) As Double(,)

array<double,2>^ Jacobian(
	array<double>^ y
)

abstract Jacobian : 
        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 doublem by n matrix containing the Jacobian. Columns that are accumulated must have the analytic part 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.
