Optimization Toolbox Release Notes

Upgrading from an Earlier Release

The Optimization Toolbox uses an options structure to access various algorithm options. The Version 2.0 (Release 11) version of the options structure may be incompatible with the 2.1 (Release 12.0) version in some cases. In particular, if you have saved an options structure in a MAT-file from Release 11 and load it into Release 12.0 you may get an error similar to

• ??? Error using ==> subsref
  Reference to non-existent field 'MaxSQPIter'.
  

To avoid this error, wrap a call to optimset around the old options structure to update it. For example,

• optionsnew = optimset(optionsold);
  

and then use the optionsnew options structure.

If you were using optimset to create your options structure, as opposed to loading it from an older MAT-file, you should not need to make any changes.
