lyapunov_set.m

关于混沌系统的李氏指数计算等混沌系统中重要参数计算的代码

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