I have a main fig file for my matlab gui, and I have created another one that I want to be able to open with the click of a button. How?

    % Open the new window - otherwindow.fig -

Ryan - if you mean that you have created another GUI (using GUIDE) and you wish to open that other GUI from within the first one, then you can just call it as

 function NewWindowButton_Callback(hObject, eventdata, handles)

 % call your other GUI
 OtherGui;

where OtherGui is the name of your other GUI (the name for the m and fig files).
