Dear all,

Is there any way to have control over the variables entering the workspace of an anonymous function? I have been experiencing some slowness lately and when I check the workspace of some of the anonymous or memoized functions I created, they contain more information that I want them to.

If the function refers to a subfunction, it contains all the information in the main function as well. Needless to say, it is the same for nested functions.

Any ideas?

You can try the following tool

but read the disclaimers.

Anonymous/nested functions can only slow things down when you try to export handles to them from the workspace where they were created. Either you're returning the handle from a function, saving it to a .mat file, or sending it to a parfor worker.
