MATLAB: How to open the workspace editor as a table for user to edit data values in a GUI

MATLAB

In a GUI, I want to modify the values of variables in the current workspace without using breakpoints or traversing to the workspace window. How can I pop the workspace out as an editable table?

Best Answer

The ability to open a separate workspace editor from a GUI is currently unavailable in MATLAB 7.6 (R2008a)

As a workaround, UITABLE can be used to display values of variables in the current workspace and get new values from the user.

This is expected behavior. OPENVAR opens variables that live in the current workspace, and updates itself as the workspace changes. Variables that exist in 'alternate' workspaces (such as callback workspaces) are only accessible as long as that alternate workspace remains in scope (current workspace). By default, the 'base' workspace is in scope during regular execution of the callback. The callback workspace comes into scope when the program is executed in debug mode.

As a workaround, use debug mode to ensure that the callback workspace remains in scope when OPENVAR is called.

You can also use the EVALIN function along with the OPENVAR function in the callback of the uicontrol to open the base workspace variable in the array editor from the GUI. Here is a simple example that shows how this can be implemented.

function UI_test
uicontrol('style','pushbutton', 'callback',@clbk)
    function clbk(source,eventdata)
        evalin('base','openvar(''X'')')  % X being a variable in the base workspace
    end
end
