EJEMPLO 2:

function varargout = untitled2(varargin)

% UNTITLED2 MATLAB code for untitled2.fig

%      UNTITLED2, by itself, creates a new UNTITLED2 or raises the existing

%      singleton*.

%

%      H = UNTITLED2 returns the handle to a new UNTITLED2 or the handle to

%      the existing singleton*.

%

%      UNTITLED2('CALLBACK',hObject,eventData,handles,...) calls the local

%      function named CALLBACK in UNTITLED2.M with the given input arguments.

%

%      UNTITLED2('Property','Value',...) creates a new UNTITLED2 or raises the

%      existing singleton*.  Starting from the left, property value pairs are

%      applied to the GUI before untitled2_OpeningFcn gets called.  An

%      unrecognized property name or invalid value makes property application

%      stop.  All inputs are passed to untitled2_OpeningFcn via varargin.

%

%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one

%      instance to run (singleton)".

Creación de apps con interfaces gráficas de usuario en MATLAB

Las GUI (también conocidas como interfaces gráficas de usuario o interfaces de usuario) permiten un control sencillo (con uso de ratón) de las aplicaciones de software, lo cual elimina la necesidad de aprender un lenguaje y escribir comandos a fin de ejecutar una aplicación.

Las apps de MATLAB son programas autónomos de MATLAB con un frontal gráfico de usuario GUI que automatizan una tarea o un cálculo. Por lo general, la GUI incluye controles tales como menús, barras de herramientas, botones y controles deslizantes. Muchos productos de MATLAB, como Curve Fitting Toolbox, Signal Processing Toolbox y Control System Toolbox, incluyen apps con interfaces de usuario personalizadas. También es posible crear apps personalizadas propias, incluidas las interfaces de usuario correspondientes, para que otras personas las utilicen.

Creación de una GUI de MATLAB de forma interactiva

GUIDE (entorno de desarrollo de GUI) proporciona herramientas para diseñar interfaces de usuario para Apps personalizadas. Mediante el editor de diseño de GUIDE, es posible diseñar gráficamente la interfaz de usuario. GUIDE genera entonces de manera automática el código de MATLAB para construir la interfaz, el cual se puede modificar para programar el comportamiento de la app.

Creación de una GUI de MATLAB de forma programática

A fin de ejercer un mayor control sobre el diseño y el desarrollo, también se puede crear código de MATLAB que defina las propiedades y los comportamientos de todos los componentes. MATLAB contiene funcionalidad integrada que le ayudará a crear la GUI para su app de forma programática. Cabe la posibilidad de agregar cuadros de diálogo, controles de interfaz de usuario (como botones y controles deslizantes) y contenedores (como paneles y grupos de botones).

EJEMPLOS:

clc;

clear all;

N=input('ingrese el numero del vector A:');

cont=1

%ingreso de elementos al vector

while(cont<=N)

    A(cont)=input('ingrese un numero:');

    cont=cont+1;

end

%Ordenar el vector

for(i=1:N-1)

    for(j=i+1:N)

        if(A(i)>A(j))

            Aux= A(i);

            A(i)=A(j);

            A(j)=Aux;

        end

    end

end

%visualizar de manera

%ascendente

for(k=1:N)

    disp(A(k));

end

%visualizar de manera

%descendente

for(p=N:-1:1)

    disp(A(p));

end
