+% ITAVA_EXPERIMENTAL_GUI MATLAB code for itaVA_experimental_gui.fig
+% ITAVA_EXPERIMENTAL_GUI, by itself, creates a new ITAVA_EXPERIMENTAL_GUI or raises the existing
+% singleton*.
+%
+% H = ITAVA_EXPERIMENTAL_GUI returns the handle to a new ITAVA_EXPERIMENTAL_GUI or the handle to
+% the existing singleton*.
+%
+% ITAVA_EXPERIMENTAL_GUI('CALLBACK',hObject,eventData,handles,...) calls the local
+% function named CALLBACK in ITAVA_EXPERIMENTAL_GUI.M with the given input arguments.
+%
+% ITAVA_EXPERIMENTAL_GUI('Property','Value',...) creates a new ITAVA_EXPERIMENTAL_GUI or raises the
+% existing singleton*. Starting from the left, property value pairs are
+% applied to the GUI before itaVA_experimental_gui_OpeningFcn gets called. An
+% unrecognized property name or invalid value makes property application
+% stop. All inputs are passed to itaVA_experimental_gui_OpeningFcn via varargin.
+%
+% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
+% instance to run (singleton)".
