Hello

Well I have a question to ask..

suppose I have the matlab code above:

plot(t,y); grid;

z=-4;p=[-2+5j -2-5j];k=6.5;

[num den]=zp2tf(z,p,k);

t=0:0.01:4;

[y,x]=step(num,den,t);

how can i find the rise time,overshoot?

are there formulas?

is there a way to find them in matlab?

thank you
