derivat

dérivée d'une matrice de polynômes

Séquence d'appel

pd=derivat(p)

Paramètres

p

polynôme, matrice de polynômes ou de fractions rationnelles

Description

Calcule la dérivée des polynômes ou fractions rationnelles contenus dans les termes de la matrice p.

Exemples

s=poly(0,'s');
derivat(1/s)  // -1/s^2;
p1 = poly([1 -2 1], 'x', 'coeff')
derivat(p1)
p2 = poly([1 -4 2], 'y', 'coeff')
derivat(p2)
p3 = poly(ones(1, 10), 'z', 'coeff')
derivat(p3)
p4 = poly([-1 1], 't', 'roots')
derivat(p4)
s = %s; p5 = s^{-1} + 2 + 3*s
derivat(p5)
