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