Ejemplo de uso del GUIDE de Matlab:
Formulario para desarrollar gráficos utilizando la forma: surf, mesh y contour de tres funciones:peaks, membrane y sinc.
function varargout = simple_gui(varargin)
% SIMPLE_GUI M-file for simple_gui.fig
% SIMPLE_GUI, by itself, creates a new SIMPLE_GUI or raises the existing
% singleton*.
%
% H = SIMPLE_GUI returns the handle to a new SIMPLE_GUI or the handle to
% the existing singleton*.
%
% SIMPLE_GUI('CALLBACK',hObject,eventData,handles,...) calls the local
%function named CALLBACK in SIMPLE_GUI.M with the given input arguments.
%
% SIMPLE_GUI('Property','Value',...) creates a new SIMPLE_GUI or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before simple_gui_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. Allinputs are passed to simple_gui_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
