function varargout = latihan_8(varargin)
% LATIHAN_8 MATLAB code for latihan_8.fig
%      LATIHAN_8, by itself, creates a new LATIHAN_8 or raises the existing
%      singleton*.
%
%      H = LATIHAN_8 returns the handle to a new LATIHAN_8 or the handle to
%      the existing singleton*.
%
%      LATIHAN_8('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in LATIHAN_8.M with the given input arguments.
%
%      LATIHAN_8('Property','Value',...) creates a new LATIHAN_8 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before latihan_8_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to latihan_8_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
