New Optimization Tool

The Optimization Tool is a graphical user interface (GUI) for performing common

optimization tasks with the Optimization Toolbox. Using the optimtool, you can do the

following:

• Select a solver and define your optimization problem.

• Set and inspect optimization options and their default values.

• Run problems and visualize results.

• Import and export problem definitions, algorithm options, and results between the

MATLAB workspace and the Optimization Tool.

• Automatically generate M-code to capture, automate, and recreate your problem.

• Access built-in help.

Plot Functions Option Added

You can now specify the PlotFcns option in the optimset function or using the

Optimization Tool for use with an Optimization Toolbox solver. With this option, you

can plot various measures of progress while the algorithm executes. You can select from

several predefined plots, or you can write your own.

Output Function Option Enhanced to Accept Multiple Functions

You can now specify more than one output function in the OutputFcn option.

Changes to the Output Function

The output function input x and fields in the optimValues structure have the following

changes that address bugs in previous releases:

• residual now returns the residual vector for lsqnonlin and lsqcurvefit.

• resnorm contains the sum of squares and has been added for lsqnonlin and

lsqcurvefit. The previous field fval has been removed for these functions.

• procedure has been removed for lsqnonlin, lsqcurvefit, and fsolve.

• x now returns the expected shape and size for fgoalattain and fminimax.
