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