[MATLAB][TEMA] Implementare GUI

Implementa?i o interfa?ă grafică prin care să realiza?i un studiu al modula?iei MF(evolu?ie în timp ?i in frecven?ă). Se va urmări ca elementele AMPLITUDINE, FRECVEN?Ă, FRECV.PURTĂTOARE, FRECV.deESANTIONARE, NUMĂRUL DE PUNCTE FFT, să fie elemente editabile.


pana acum am scris asta :

function varargout = untitled1(varargin)
% UNTITLED1 M-file for untitled1.fig
%	  UNTITLED1, by itself, creates a new UNTITLED1 or raises the existing
%	  singleton*.
%
%	  H = UNTITLED1 returns the handle to a new UNTITLED1 or the handle to
%	  the existing singleton*.
%
%	  UNTITLED1('CALLBACK',hObject,eventData,handles,...) calls the local
%	  function named CALLBACK in UNTITLED1.M with the given input arguments.
%
%	  UNTITLED1('Property','Value',...) creates a new UNTITLED1 or raises the
%	  existing singleton*.  Starting from the left, property value pairs are
%	  applied to the GUI before untitled1_OpeningFcn gets called.  An
%	  unrecognized property name or invalid value makes property application
%	  stop.  All inputs are passed to untitled1_OpeningFcn via varargin.
%
%	  *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%	  instance to run (singleton)".
%
% See also: GUIDE, GUIDATA, GUIHANDLES

% Edit the above text to modify the response to help untitled1
