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