Program Matlab deteksi Tepi

Ini adalah script dengan matlab untuk membuat program deteksi tepi.
function varargout = deteksi_tepi(varargin)
% DETEKSI_TEPI M-file for deteksi_tepi.fig
% DETEKSI_TEPI, by itself, creates a new DETEKSI_TEPI or raises the existing
% singleton*.
%
% H = DETEKSI_TEPI returns the handle to a new DETEKSI_TEPI or the handle to
% the existing singleton*.
%
% DETEKSI_TEPI('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in DETEKSI_TEPI.M with the given input arguments.
%
% DETEKSI_TEPI('Property','Value',...) creates a new DETEKSI_TEPI or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before deteksi_tepi_OpeningFunction gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to deteksi_tepi_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
