function varargout = pic_1(varargin)
% PIC_1 MATLAB code for pic_1.fig
%      PIC_1, by itself, creates a new PIC_1 or raises the existing
%      singleton*.
%
%      H = PIC_1 returns the handle to a new PIC_1 or the handle to
%      the existing singleton*.
%
%      PIC_1(\'CALLBACK\',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in PIC_1.M with the given input arguments.
%
%      PIC_1(\'Property\',\'Value\',...) creates a new PIC_1 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before pic_1_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop_music.  All inputs are passed to pic_1_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE\'s Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
