Options are a way of combining a set of name-value pairs. They are useful because they allow you to:
Tune or modify the optimization process.
Select extra features, such as output functions and plot functions.
Save and reuse settings.
They simplify solver syntax—you don't have to include a lot of name-value pairs in a call to a solver.
To see how to set and change options, see Set and Change Options.
For an overview of all options, including which solvers use each option, see Optimization Options Reference.
