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