Python中的 numpy.polydiv()

numpy.polydiv()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。

Syntax : numpy.polydiv(p1, p2)
Parameters :
p1 : [array_like or poly1D]Coefficients of dividend polynomial.
p2 : [array_like or poly1D]Coefficients of divisor polynomial.

Return:
q : [ndarray]Coefficients of quotient.
r : [ndarray]Coefficients of remainder.

# importing libraries
import numpy as np
import pandas as pd
  
# 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)
