%EJERCICIO4 M-file for Ejercicio4.fig
%      EJERCICIO4, by itself, creates a new EJERCICIO4 or raises the existing
%      singleton*.
%
%      H = EJERCICIO4 returns the handle to a new EJERCICIO4 or the handle to
%      the existing singleton*.
%
%      EJERCICIO4('Property','Value',...) creates a new EJERCICIO4 using the
%      given property value pairs. Unrecognized properties are passed via
%      varargin to Ejercicio4_OpeningFcn.  This calling syntax produces a
%      warning when there is an existing singleton*.
%
%      EJERCICIO4('CALLBACK') and EJERCICIO4('CALLBACK',hObject,...) call the
%      local function named CALLBACK in EJERCICIO4.M with the given input
%      arguments.
