function varargout = Kgpj(varargin)
%KGPJ M-file for Kgpj.fig
%      KGPJ, by itself, creates a new KGPJ or raises the existing
%      singleton*.
%
%      H = KGPJ returns the handle to a new KGPJ or the handle to
%      the existing singleton*.
%
%      KGPJ('Property','Value',...) creates a new KGPJ using the
%      given property value pairs. Unrecognized properties are passed via
%      varargin to Kgpj_OpeningFcn.  This calling syntax produces a
%      warning when there is an existing singleton*.
%
%      KGPJ('CALLBACK') and KGPJ('CALLBACK',hObject,...) call the
%      local function named CALLBACK in KGPJ.M with the given input
%      arguments.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
