SolvableMultivariableFunction.EvaluateDerivative Method (Double[], Boolean, SolvableMultivariableFunctionResults, ITrackCalculationProgress)

Evaluates the Jacobian of this function. The default implementation of this method will numerically compute the Jacobian. To do that, the value of the function at the variables will be computed.

Parameters

variables: Type:System.Double[]
The values to compute the Jacobian at.
multithreaded: Type: System.Boolean
Should the evaluation be done using as many cores as possible.
valueResults: Type: AGI.Foundation.NumericalMethods.SolvableMultivariableFunctionResults
The evaluated value of the function at the variables. If this is null then this function will be evaluated at the variables as part of the default evaluation of the Jacobian.
progressTracker: Type: AGI.Foundation.ITrackCalculationProgress
An optional progress tracker.

Return Value

Type: SolvableMultivariableFunctionDerivativeResults
The Jacobian and any other relevant results evaluated while evaluating the derivative of this function.
