MATLAB: Clean variables of worskpace from GUIDE

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.

MATLAB: How to move a variable from the global workspace to a local workspace

There is no native way to accomplish this, but the function below should move the variable from the global workspace to the workspace from which the function was called.

function moveToLocal( str )

% MOVETOLOCAL Move a variable form the global to the local workspace

% str should be the name of the variable that is already in the global workspace

% that you wish to move to the local workspace of the calling function.

% The variable will still exist in the global workspace but in the local

% workspace of the calling function the variable will be scoped locally

eval(['global ' str]) % bring the variable in from the global workspace

k=eval(str); % fetch the value of the variable from the global workspace

evalin( 'caller', ['clear ' str]); % clear the value from the caller's workspace

assignin( 'caller', str, k); % assign the value into the caller's local workspace
