2-3

That method still works. But when using optimoptions, you cannot set the parameter

in the Algorithm option, and instead must use the InitDamping option, such as

options = optimoptions(@fsolve,'Algorithm','levenberg-marquardt','InitDamping',0.1);

Changing default algorithm for fminunc

The fminunc default algorithm will change to 'quasi-newton' in a future release.

Compatibility Considerations

fminunc now warns when you run it in cases where the default behavior will change.

For details, see the fminunc function reference page or fminunc Algorithms.

Mixed-integer linear programming example

There is a new featured example of mixed-integer linear programming, Optimal Dispatch

of Power Generators.

Two linprog algorithms will be removed in the future

The linprog 'active-set' and 'simplex' algorithms warn that they will be removed

in a future release.

Compatibility Considerations

To avoid this warning, choose the 'interior-point' or 'dual-simplex' algorithms

using optimoptions.

Two fminunc options will be removed in the future

fminunc now warns that the InitialHessMatrix and InitialHessType options will

be removed in a future release.

Compatibility Considerations

To avoid these warnings, do not set values for these options. The Optimization app no

longer has these options.
