Callbacks in Applications

If you have a user interface that executes many callbacks through the MATLAB® engine, force these callbacks to be evaluated in the context of the base workspace. Use evalin to specify the base workspace for evaluating the callback expression. For example:

engEvalString(ep,"evalin('base', expression)")

Specifying the base workspace ensures MATLAB processes the callback correctly and returns results for that call.

This advice does not apply to computational applications that do not execute callbacks.
