Python Numpy np.legadd()方法
np.legadd() 方法用于将一个Legendre数列加到另一个数列上。它返回两个Legendre数列的总和 c1 + c2。
语法: np.legadd(c1, c2)
参数:
c1, c2 : [ array_like ] Legendre系列系数的一维数组,从低到高排序。
返回: [ndarray] 代表Legendre数列的和的数组。

# numpy.legadd() 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 = (1, 3, 5)
s2 = (2, 4, 6)
# using np.legadd() method
res = geek.legadd(s1, s2)
# Resulting legendre series
print (res)
输出:
[ 3. 7. 11.]
