Some very basic examples
PT1/lowpass filter step response
Code: Creating a transfer function and plotting its response 
T1=0.4; # time constant
P=tf([1], [T1 1]) # create transfer function model
step(P,2) # plot step response
#add some common markers like the tangent line at the origin, which crosses lim(n>inf) f(t) at t=T1
hold on
plot ([0 T1], [0 1],"g")
plot ([T1 T1], [0 1],"k")
plot ([0 T1], [11/e 11/e],"m")
hold off

Try also bode(P)! (a first order lowpass filter has 3db magnitude at f=1/T1)
