MATLAB: GUI variables not going to workspace

guiload

Hello,

When running a GUI program I cannot get the variables used in the GUI to show up on my workspace. Is there a reson for this?

Those variables are in their own workspace. Use assignin to get them to the base if you need them there:

doc assignin

or less dangerously you could set them to application data using setappdata and then have a function that you call from the command line that retrieves them from application data ( getappdata) so that you lower the risk of overwriting important other variables.

doc setappdata
doc getappdata

You can use the EVALIN function to load a .MAT file into the base workspace from a function. For example, you can place the following code in the callback function of a push button in your GUI:

filename = uigetfile('*.mat');
command = sprintf('load(''%s'')', filename);
evalin('base', command);

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.
