I have created a GUI. I want to do like Whenever that GUI starts it should only execute files from predefined path in it..
For that i want to assign path for it.. So, where i have to assign it and what will be command.?
Whether at below opening function or somewhere else.?

Yes, you can hard code a path and use cd() to change into this path. It would be safer to store this path in the handles struct and use absolute file names instead, because otherwise and cd() command in a Timer, another GUI or in the command line would confuse your GUI application.
It is user friendly not to hard code a path in the sourcecode of a GUI. Better add a textfield to the GUI, which conatins the current focussed folder and allow the user to change it. Whenever the value is modified, it is written as MAT file to the folder prefdir, such that at opening the GUI you can obtain the former value from this location again:
% In Opening function: try Data = load(fullfile(prefdir, 'MyGUIFolder.mat')); myFolder = Data.myFolder; catch % Not existing yet: myFolder = pwd; end handles.myFolder = myFolder; guidata(figureHandle, myFolder);
% In callback: function myXYZ_callback(hObject, EventData, handles) handles = guidata(hObject); disp(handles.myFolder);
% In callback of the text field, which contains the folder: function myText_callback(hObject, EventData, handles) myFolder = get(hObject, 'String') if exist(myFolder, 'dir') ~= 7 set(hObject, 'Color', 'r'); % Or what ever return; end set(hObject, 'Color', 'k'); % Or what ever save(fullfile(prefdir, 'MyGUIFolder.mat'), 'myFolder');
