derivat

有理行列の微分

呼び出し手順

pd = derivat(p)

パラメータ

p, pd

多項式または有理行列

説明

多項式または有理関数行列のダミー変数に関する微分を計算します.

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)
