hi everyone
I want to create improved lorenz code , but its doesnt work well
could someone help me , please
this is my code
function dy= lorenz(t,y)
a = 8/3;
b = 25;
c = 10;
d = 5.3;
e = 17.5;
f = 10.5;
g = 13.3;
h = 14;
if cos(5.3*t)>=0
p=1;
else
p=-1;
end
dy=zeros(3,1);
dy(1)=a*y(1)+p*y(2)*y(3);
dy(2)=y(3)*b-y(3)*c*cos(d*t) - b*y(2)+y(2)+c*cos(d*t);
dy(3)= -1*p*y(1)*y(2)-(e*cos(d*t)+f)*y(2)+(g-h*y(3)*(cos(d*t)));
end

If I follow the instructions from scratch, I get the same output as you. So why to you assume that the diagram of the top is the correct solution? It looks like the standard Lorenz attractor, but the formula is something different.

The test contains cos(dt), but your code only cos(t).

I still do not see a convincing reason to assume, that there is any problem. I've written some code to solve the answer and get the same output as you (as far as I can see). Why do you think that your code is wrong?
