%z

多項式を定義する際に使用される変数.

呼び出し手順

%z

説明

%z はデフォルトで複素数多項式, z = poly(0, "z")を表します. この変数は多項式を作成する際に使用されます.

p = %z^2 + 2 * %i *%z -1
roots(p)
coeff(p)
z = poly(0, "z");
p1 = z^2 + 2*%i*z -1
roots(p1)
coeff(p1)

参照

  • poly — Polynomial definition from given roots or coefficients, or characteristic to a square matrix.
  • coeff — 多項式行列の係数
  • roots — 多項式の根
