rt.m

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 out = rt(in,axe,angle);
% translation

out = in;
if axe==1,
        out(:,2:3) = out(:,2:3)*[[cos(angle),sin(angle)];[-sin(angle),cos(angle)]]';
elseif axe==2,
        temp = [out(:,1),out(:,3)];
        temp = temp*[[cos(angle),sin(angle)];[-sin(angle),cos(angle)]]';
        out(:,1) = temp(:,1);
        out(:,3) = temp(:,2);
end;
