Syntax
k = polyder(p) k = polyder(a,b) [q,d] = polyder(b,a)
Description
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.
k = polyder(p)
returns the derivative of the polynomial p.
k = polyder(a,b)
returns the derivative of the product of the polynomials a and b.
[q,d] = polyder(b,a)
returns the numerator q and denominator d of the derivative of the polynomial quotient b/a.
Examples
a = [3 6 9];
b = [1 2 0];
k = polyder(a,b)
k =
12 36 42 18
This result represents the polynomial
