Python| Numpy np.legdiv() 方法

np.legdiv()方法用于将一个勒让德级数除以另一个。它返回两个勒让德级数c1 / c2.

Syntax : np.legdiv(c1, c2)
Parameters:
c1, c2 :[ array_like ] 1-D arrays of Legendre series coefficients ordered from low to high.

Return : [ndarray] Legendre series coefficients representing the quotient and remainder.

代码#1：

# Python program explaining
# numpy.legdiv() method 
    
# importing numpy as np  
# and numpy.polynomial.legendre module as geek 
import numpy as np 
import numpy.polynomial.legendre as geek
    
# Legendre series coefficients
  
s1 = (2, 4, 8) 
s2 = (1, 3, 5)   
    
# using np.legdiv() method 
res = geek.legdiv(s1, s2) 
  
# Resulting legendre series
print (res) 

输出：

(array([ 1.6]), array([ 0.4, -0.8]))
