Python Numpy np.lagadd()方法

np.lagadd()方法用于将一个拉盖尔数列加到另一个上。它返回两个拉盖尔数列的总和 c1 + c2。

语法: np.lagadd(c1, c2)
参数:
c1, c2 : [ array_like ] 拉盖尔数列系数的一维数组，从低到高排序。

返回： [ndarray] 代表它们之和的拉盖尔序列的数组。

代码#1：

# Python program explaining
# numpy.lagadd() method 
    
# importing numpy as np  
# and numpy.polynomial.laguerre module as geek 
import numpy as np 
import numpy.polynomial.laguerre as geek
    
# Laguerre series coefficients
s1 = (1, 3, 5) 
s2 = (2, 4, 6)    
    
# using np.lagadd() method 
res = geek.lagadd(s1, s2) 
  
# Resulting laguerre series
print (res)

输出:

[  3.   7.  11.]
