Clean variables of worskpace from GUIDE

Hi Everyone!

I have a problem with a code in GUIDE. I want clean some variables of workspace that previously I saved from GUIDE. To save variables in workspace, I've used this code:

if true
  % assignin('base', 'VHA', VHA);
end

And to obtain variables from workspace i use evalin

if true
  % evalin('base','VHA');
end

I know that 'clear' doesn't work in GUIDE. So ¿which should to use? I don't want clean all variables.

Messing around with other workspaces is a design flaw.

You can send commands to base workspace using the evalin() function as you mentioned. For example you can say:

 evalin('base','who')

and to clear a variable myvarinbase say

 evalin('base','clear myvarinbase')

Note that

 clear var1 var2

will remove variables var1 var2 from the current workspace, not necessarily base workspace, if it is called from inside a function like a GUI.

Thank you for your suggestion of evalin. This allowed me to reduce a lot of code because I was using assignin.

I used

    evalin('base','clear n')

for clean the N variable or

    evalin('base','clear all')

for clean all variables of workspace.
