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