Usage
The polyder function returns the polynomial coefficients resulting
from differentiation of polynomial p. The syntax for its use is either
pder = polyder(p)
for the derivitave of polynomial p, or
convp1p2der = polyder(p1,p2)
for the derivitave of polynomial conv(p1,p2), or still
[nder,dder] = polyder(n,d)
for the derivative of polynomial n/d (nder is the numerator
and dder is the denominator). In all cases the polynomial
coefficients are assumed to be in decreasing degree.
