Solver Outputs and Iterative Display

Definitions and meaning of solver outputs; details of iterative display

This section helps you understand or interpret output from your solver.

Topics

Current Point and Function Value
What the x and fval outputs mean.
Exit Flags and Exit Messages
Describes the message that a solver prints at the end of its run and the associated exit flags.
Iterations and Function Counts
Gives basic information on solver progress.
First-Order Optimality Measure
An important criterion for determining whether a solution might be optimal.
Output Structures
Solver output structures, which are optional output giving details of the solver iterations.
Lagrange Multiplier Structures
Solver Lagrange multiplier structures, which are optional output giving details of the Lagrange multipliers associated with various constraint types.
Hessian Output
Describes the Hessian returned by fmincon or fminunc.
Plot Functions
Describes plot functions for displaying information on solver iterations.
Output Functions for Optimization Toolbox
Describes how to make an optimization function call an output function at each iteration.

Iterative Display
Describes iterative output you can display in the Command Window.
