SolvableMultivariableFunction.EvaluateDerivative Method (Double[], Boolean, 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. When using the default implementation, the PerturbationValues must be set.
