Hi,here are the codes.
w=[0.5:0.1:1,2];tt=0.4
figure(1)
hold on
for wn=w
num=[2*tt*wn,wn.^2];
den=[1,2*tt*wn,wn.^2];
step(num,den)
end
hold off
When I try to run it,I get the error Undefined function 'step' for input arguments of type 'double'.How can I do? Thank you!
[EDITED, Jan, please format your code - Thanks]

Tell us what shows up in your command window. What do you think step is supposed to do? Something in the Control System Toolbox, or something else?

step() is also used by the Computer Vision Toolbox, but I would say Control System is much more likely the intended application here.
