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