looks great, but the code can be much more simple!
for example,

function keep(varargin)

% variables to clear in a cell array
varlist = evalin('caller','who');
varlist = setdiff(varlist,varargin);

% make a string (separate the variable by a space)
[varlist{:,2}] = deal(' ');
varlist = varlist';
varstr = [varlist{:}];

% and clear!
evalin('caller',['clear ' varstr])

Tried with both matlab 2010 and 2012 but did not work for me. No error messages but no link between the images. Also the "brick" was required for operation so you might want to mention this at the description.
