Returns the equations evaluated at the point y. If the user does not override the EvaluateF method, then F is also used to compute the function values at the current independent variable values y_e.

Namespace: Imsl.Math
Assembly: ImslCS (in ImslCS.dll) Version: 6.5.0.0

Syntax

C#
double[] F(
	int varIndex,
	double[] y
)
Visual Basic (Declaration)
Function F ( _
	varIndex As Integer, _
	y As Double() _
) As Double()
Visual C++
array<double>^ F(
	int varIndex, 
	array<double>^ y
)

Parameters

varIndex
Type: System..::.Int32
An int indicating the index of the variable to perturb. varIndex = 1 indicates variable 1 in y[0].
y
Type: array< System..::.Double >[]()[]
A double array of length n, the point at which the Jacobian is to be evaluated.

Return Value

A double array of length m. The equations evaluated at the point y.
