Hello so am trying to plot the step response of this trasnsfer function , but am not really sure how do i need to write it down in den = part , any help would be great thanks. .
num = 1;
den = [1 2 17];

Get help by doing:
Basically, you need to expand the denominator given in image into polynomial of s. Then take the coefficients and put into den. For example, if you expand it into 2*s^2+5*s+10, then den = [2 5 10].
To expand the denominator, you can do it manually or you can use the expand function of matlab.
