Python numpy.polydiv()
numpy.polydiv()方法对两个多项式的除法进行评估,并返回多项式除法的商和余数。
语法 : numpy.polydiv(p1, p2)
参数 :
p1 :[array_like or poly1D]分红多项式的系数。
p2 :[array_like or poly1D]除数多项式的系数。
返回:
q :[ndarray]商的系数。
r :[ndarray]余数的系数。

# Constructing polynomial
p1 = np.poly1d([1, 2])
p2 = np.poly1d([4, 9, 5, 4])
print ("P1 : ", p1)
print ("\n p2 : \n", p2)
quotient, remainder = np.polydiv(p2, p1)
print("\n\nquotient : ", quotient)
print("remainder : ", remainder)
print ("\n")
# Defining ndarray
x = np.array([1, 2])
y = np.array([4, 9, 5, 4])
quotient, remainder = np.polydiv(y, x)
print("quotient : ", quotient)
print("remainder : ", remainder)
