function varargout = myproject(varargin)

% MYPROJECT M-file for myproject.fig

% MYPROJECT, by itself, creates a new MYPROJECT or raises the existing

% singleton*.

%

% H = MYPROJECT returns the handle to a new MYPROJECT or the handle to

% the existing singleton*.

%

% MYPROJECT('CALLBACK',hObject,eventData,handles,...) calls the local

% function named CALLBACK in MYPROJECT.M with the given input arguments. %

% MYPROJECT('Property','Value',...) creates a new MYPROJECT or raises the

% existing singleton*. Starting from the left, property value pairs are

% applied to the GUI before myproject_OpeningFcn gets called. An

% unrecognized property name or invalid value makes property application

% stop. All inputs are passed to myproject_OpeningFcn via varargin.

%

% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one

% instance to run (singleton)".
