Programacin en guide:

Para la implementacin del proyecto usaremos el interfaz grfico (GUIDE) que nos proporciona el

software MATLAB como se puede apreciar en la siguiente figura:

Creacin del Entorno Grafico en GUIDE

Para crear un archivo en GUIDE realizamos los siguientes pasos:

Una vez seleccionado creamos una nueva aplicacin:

De donde obtenemos lo siguiente:

Desarrollando el programa tenemos:

EL CODIGO DEL PROGRAMA ES:

function varargout = diagnostico(varargin)% DIAGNOSTICO M-file for diagnostico.fig% DIAGNOSTICO, by itself, creates a new DIAGNOSTICO or raises theexisting% singleton*.%% H = DIAGNOSTICO returns the handle to a new DIAGNOSTICO or thehandle to% the existing singleton*.%% DIAGNOSTICO('CALLBACK',hObject,eventData,handles,...) calls thelocal

% function named CALLBACK in DIAGNOSTICO.M with the given inputarguments.%% DIAGNOSTICO('Property','Value',...) creates a new DIAGNOSTICO orraises the% existing singleton*. Starting from the left, property value pairsare% applied to the GUI before diagnostico_OpeningFcn gets called. An% unrecognized property name or invalid value makes propertyapplication

% stop. All inputs are passed to diagnostico_OpeningFcn viavarargin.%% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows onlyone% instance to run (singleton)".%% See also: GUIDE, GUIDATA, GUIHANDLES

% Edit the above text to modify the response to help diagnostico
