How to delete variables fro Base workspace, from within a function?
in [Matlab]

From: Matlabuser on 17 Mar 2010 06:56 Hi all, I am trying to write a function that would delete variables from the Base workspace. So far it's not working. "clear all" or "clear global" only deletes the variables defined in the function workspace. How can I clear variables from the Base workspace? The "help" section didn't really help... thanks

The whole rational behind functions is to set up a local workspace, that is independent from the main workspace, except for input / return arguments. If you are *sure* you want to let a program get access to the main workspace - and it's a very bad idea - use a script that is called from the main workspace. Again: There are *very* good reasons why what you want to do is not easy. It is almost ceratinly not the correct way of doing whatever it is you are up to. Rune
