Optimizer.Gradient Property

Top

Description

The Gradient of the objective function. This is the partial derivative of the objective with respect to the state variables. At the beginning of the optimization process, FreeFlyer fills this array with a constant (-999) so that any derivatives the user provides using this array can be automatically detected. All derivatives that the user does not provide will be calculated numerically. When FreeFlyer calculates the derivatives numerically, the elements of the Gradient are filled in one at a time as they are calculated.

Timing Precision Mode

This page describes functionality in millisecond timing precision mode. Millisecond timing precision mode is deprecated and will be removed in a future release. We recommend that you migrate your Mission Plans to nanosecond timing precision mode.
