**np.legadd()**法是将一个勒让德系列加到另一个上。它返回两个勒让德级数 c1 + c2.的和
语法:
np.legadd(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】表示它们之和的勒让德级数的数组。
代码#1 :
# Python program explaining
# 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)
Output:
[ 3\. 7\. 11.]
代码#2 :
# Python program explaining
# 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 = (10, 20, 30, 40, 50)
s2 = (2, 4, 6, 8, 10)
# using np.legadd() method
res = geek.legadd(s1, s2)
# Resulting legendre series
print (res)
Output:
[ 12\. 24\. 36\. 48\. 60.]
