MATLAB: Clearing functions selectively, excluding ones with persistent vars

clearclearing functionsMATLAB

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.

MATLAB: How to clear locked functions from memory

The functions remain in memory because they are locked. Use the MISLOCKED function to determine if a function is locked. The locked function can be unlocked using the MUNLOCK function.

For example, if the function FISLOCK is a locked function, type the following commands at MATLAB command prompt, to identify and unlock the function:

mislocked 'fislock'  %Checks if fislock is locked
munlock 'fislock' % Do this if the reult for the previous command is 1 or true
clear all; clear functions; %Clears unlocked functions from memory
inmem

Now the function fislock will not appear in the result.

The attached file, clearmemory.m can be run to unlock and remove locked function from memory.

NOTE: These functions may be locked in memory for a reason. Unlocking and clearing can cause other issues. Before clearing a function, ensure that it indeed must cleared.
