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