% GEARS_INTERNAL_EXPORT M-file for gears_internal_export.fig
%      GEARS_INTERNAL_EXPORT, by itself, creates a new GEARS_INTERNAL_EXPORT or raises the existing
%      singleton*.
%
%      H = GEARS_INTERNAL_EXPORT returns the handle to a new GEARS_INTERNAL_EXPORT or the handle to
%      the existing singleton*.
%
%      GEARS_INTERNAL_EXPORT('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in GEARS_INTERNAL_EXPORT.M with the given input arguments.
%
%      GEARS_INTERNAL_EXPORT('Property','Value',...) creates a new GEARS_INTERNAL_EXPORT or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before gears_internal_export_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to gears_internal_export_OpeningFcn via varargin.
