Python 中的 numpy.polydiv()
numpy . poldiv()方法计算两个多项式的除法，并返回多项式除法的商和余数。
语法: numpy.polydiv(p1，p2) 参数: P1:【array _ like 或 poly1D】被除数多项式的系数。 p2:【array _ like 或 poly1D】除数多项式的系数。
返回: q:【ndarray】商的系数。 r:【n 数组】余数系数。

# 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)
