function varargout = homework2(varargin)
% HOMEWORK2 M-file for homework2.fig
%      HOMEWORK2, by itself, creates a new HOMEWORK2 or raises the existing
%      singleton*.
%
%      H = HOMEWORK2 returns the handle to a new HOMEWORK2 or the handle to
%      the existing singleton*.
%
%      HOMEWORK2(‘CALLBACK‘,hObject,eventData,handles,...) calls the local
%      function named CALLBACK in HOMEWORK2.M with the given input arguments.
%
%      HOMEWORK2(‘Property‘,‘Value‘,...) creates a new HOMEWORK2 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before homework2_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to homework2_OpeningFcn via varargin.
