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