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