numpy.polydiv(p1，p2)方法計算兩個多項式的除法，並返回多項式除法的商和餘數。
參數：
p1:[array_like or poly1D]Coefficients of dividend polynomial.
p2:[array_like or poly1D]Coefficients of divisor polynomial.返回：
q:[ndarray]Coefficients of quotient.
r:[ndarray]Coefficients of remainder.

# 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 ("\n")
# Defining ndarray
x = np.array([1, 2])
y = np.array([4, 9, 5, 4])
quotient, remainder = np.polydiv(y, x)
