用matlab实现利用统计混沌方法解决非线性系统时间序列预测的问题

function draxis(translation)
% The function:
% 
%       draxis(translation)
% 
% draws Cartesian axis with 3 arrows 
% in the current 3-dimensional axis. 
% Optional arg <translation> allows 
% to translate the axis; default is [0,0,0]. 

if nargin<1, translation = [0,0,0]; end;

hold on;
