k = polyder(p)
k = polyder(a,b)
[q,d] = polyder(b,a)
The polyder function calculates the derivative of polynomials, polynomial products, and polynomial quotients. The operands a, b, and p are vectors whose elements are the coefficients of a polynomial in descending powers.
The derivative of the product
is obtained with
a = [3 6 9]; b = [1 2 0]; k = polyder(a,b) k = 12 36 42 18
This result represents the polynomial
