李萨如曲线

上一篇 / 下一篇  2018-10-24 15:28:44

两互相垂直的,频率成一定整数比例关系的简谐振动合成,合振动为有一定规则的稳定的闭合曲线,称李萨如曲线。运行程序,令a=pi/3,k=3可得李萨如曲线

function varargout = zhuwx(varargin)

% ZHUWX M-file for zhuwx.fig

%      ZHUWX, by itself, creates a new ZHUWX or raises the existing

%      singleton*.

%

%      H = ZHUWX returns the handle to a new ZHUWX or the handle to

%      the existing singleton*.

%

%      ZHUWX('CALLBACK',hObject,eventData,handles,...) calls the local

%      function named CALLBACK in ZHUWX.M with the given input arguments.

%

%      ZHUWX('Property','Value',...) creates a new ZHUWX or raises the

%      existing singleton*.  Starting from the left, property value pairs are

%      applied to the GUI before zhuwx_OpeningFunction gets called.  An

%      unrecognized property name or invalid value makes property application

%      stop.  All inputs are passed to zhuwx_OpeningFcn via varargin.

%

%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one

%      instance to run (singleton)".
