用 Matlab 编程模拟 李萨如曲线 两互相垂直的

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)".
