Displays the gradients of the objective function (where available) for an estimated system object.

The (default) summary form shows the value of the gradient vector at the estimated parameter values (if valid estimates exist) or at the current coefficient values. Evaluating the gradients at current coefficient values allows you to examine the behavior of the objective function at starting values. The tabular form shows a spreadsheet view of the gradients for each observation. The graphical form shows this information in a multiple line graph.
