workspace & GUI

Hi, I have a some data in the workspace which is data1 = <4x4x13 int32).

If I want to clear this from the workspace, I can do so by typing "clear data1" in the command window. However, when I write this into a GUI pushbutton call back, it doesn't do anything.

clear data1;
delete(get(handles.axes1,'children'));    % clear axes 1   
set(handles.uitable1, 'Data', []);        % clears uitable

everything else works (uitable, axes1) but not the workspace!

That's because it's calling it in the workspace of the callback function, not the base work space. This is what you want:

evalin('base','clear data1');

Thanks, does the same apply for reassigning data in the workspace to another name using the callback.

last = data1

does not work.

Done it:

evalin('base','Last = data1')

Yes. Use assignin to accomplish that task.

Beware however, this can all be dangerous as you may overwrite/clear something unintentionally.
