Clearing Global variables... except for.

Hey all,
I wish to clear all my global variables apart from two. So I've generated a cell array of strings that contain all my global variables and removed the two I wish to save:
globals = who('global');
globals = globals(~strcmpi(globals,'waitGUI'));
globals = globals(~strcmpi(globals,'decayFig'));
This is where I'm stuck. How do I clear all the variables who's names of the variables are strings within the cell array "globals"? Thanks!

To remove the variables locally
clear(globals{:})
to remove them globally
clear('global', var{:})
You should also look into the regexp support of clear and the -except flag.
clear -global -except waitGUI decayFig

Sorry I thought you wanted to do it locally. To do it globally is essentially the same, except you need the global flag. You really should read the documentation of clear, since there are a number of better ways of doing this.

A meta-answer: Avoid working with GLOBALS. There are always better solutions which do not make the debugging a trip to hell.

Here's one way. Just save what you want into local variables, then destroy all globals, then recreate the globals you want:
% Save into local variables.
saved_waitGUI = waitGUI;
saved_decayFig = decayFig;
% Clear all globals
clear global;
% Redeclare globals
global waitGUI;
global decayFig;
% Restore the globals we wanted to keep
waitGUI = keep_waitGUI;
decayFig = keep_decayFig;
