原文:https://www . geesforgeks . org/python-numpy-NP-legmul-method/
**np.legmul()**法是将一个勒让德级数相乘得到另一个。它返回两个勒让德系列 c1 * c2.的乘积
语法:
np.legmul(c1, c2)参数: c1、C2:【array _ like】勒让德级数系数的一维数组从低到高排序。返回:【ndarray】表示它们乘积的勒让德级数系数。
代码#1 :
# Python program explaining
# numpy.legmul() 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.legmul() method
res = geek.legmul(s1, s2)
# Resulting Legendre series
print (res)
Output:
[ 14\. 27.6 37.42857143 26.4 20.57142857]
代码#2 :

# Legendre series coefficients
s1 = (10, 20, 30, 40, 50)
s2 = (2, 4, 6, 8, 10)
# using np.legmul() method
