Clearing functions selectively, excluding ones with persistent vars

Hi everyone,

I am having memory issues with version 7 (2004) and have to twist and twirl to get around it. I want to clear all the functions at some point, except ones that have persistent variables in them. I create an automatic list for those function names, and find the rest of the function names, but I cannot use the clear command to remove those functions from memory, due to type mismatch. Any ideas on this?

---> clear(setdiff(inmem,pers_fList)) % (pers_fList : function list to keep)

'setdiff' outputs cell array, which 'clear' does not accept. I can't convert it appropriately. Could there be a simple solution to this? Thanks !

Stephanie - try creating the cell array as

 funcsToClear = setdiff(inmem,pers_fList);

and then clear it with

 clear(funcsToClear{:});

I was able to do the above with a similar cell array of strings.

Thanks Geoff, It worked ! I realize I've known both solutions, but seems like I wasn't able to recall. Thank you both..

Another approach is to use the mlock function inside of the functions that you want to protect from being cleared. You can then call clear functions without having to worry about keeping a list.

Thanks a lot John ! This looks like a more pro solution. Below is handier for now :)
