[num den]=pade(100,1)
num= -s+0.02 -> one zero at s=0.02
den= s+0.02 -> one pole at s=-0.02
You can see the zeros and poles like this pzmap(tf(num,den)) , or the step response step(tf(num,den)), tip: change the order from 1 to 2 and see what happens to the step response.
From the documentation of the pade function:
The row vectors num and den contain the numerator and denominator coefficients in descending powers of s. Both are Nth-order polynomials.
