23% GEOMETRY_CALIB M-file for geometry_calib.fig
24%      GEOMETRY_CALIB, by itself, creates a MenuCoord GEOMETRY_CALIB or raises the existing
25%      singleton*.
26%
27%      H = GEOMETRY_CALIB returns the handle to a MenuCoord GEOMETRY_CALIB or the handle to
28%      the existing singleton*.
29%
30%      GEOMETRY_CALIB('CALLBACK',hObject,eventData,handles,...) calls the local
31%      function named CALLBACK in GEOMETRY_CALIB.M with the given input arguments.
32%
33%      GEOMETRY_CALIB('Property','Value',...) creates a MenuCoord GEOMETRY_CALIB or raises the
34%      existing singleton*.  Starting from the left, property value pairs are
35%      applied to the GUI before geometry_calib_OpeningFunction gets called.  An
36%      unrecognized property name or invalid value makes property application
37%      stop.  All inputs are passed to geometry_calib_OpeningFcn via varargin.
38%
39%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
40%      instance to run (singleton)".
