Python| Numpy np.lagadd() 方法
np.lagadd()
方法用于将一个拉盖尔级数相加。它返回两个拉盖尔级数c1 + c2.
Syntax : np.lagadd(c1, c2)
Parameters:
c1, c2 :[ array_like ] 1-D arrays of Laguerre series coefficients ordered from low to high.
Return : [ndarray] Array representing the Laguerre series of their sum.

# 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)
