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