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