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