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