optimoptions function for setting options with compact and

comprehensive display

The new optimoptions function creates and modifies options for all solvers except the

base MATLAB

solvers fminbnd, fminsearch, fzero, and lsqnonneg. Continue to use

optimset for those functions.

optimoptions organizes options by solver, with a more focused and comprehensive

display than optimset:

• Creates and modifies only the options that apply to a solver

• Shows your option choices and default values for a specific solver/algorithm

• Displays links for more information on solver options and other available solver

algorithms

For details, see the optimoptions page, or Set Options.

Compatibility Considerations

If you export options or a problem from the Optimization Tool, the options are an object

as created by optimoptions. Therefore, earlier software versions cannot import the

options or problem. This consideration does not apply to the base MATLAB solvers,

which continue to encapsulate options as a structure.

Algorithm option replaces LargeScale option

Use the Algorithm option to select the algorithm in all solvers that have multiple

algorithms. In a future release, solvers will no longer use the LargeScale option. The

linprog Simplex option will also change to the Algorithm option.

Compatibility Considerations

Update options as follows.

region'
