Python | Numpy np.lagsub()方法
原文:https://www . geesforgeks . org/python-numpy-NP-lag sub method/
**np.lagub()**法是将一个拉盖尔级数减去另一个。它返回两个拉盖尔系列T1】的差值
语法:
np.lagub(c1, c2)参数: c1、C2:【array _ like】从低到高排序的拉盖尔级数系数一维数组。返回:【ndarray】代表其差值的拉盖尔级数系数。
代码#1 :
# Python program explaining
# numpy.lagsub() 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 = (2, 4, 8)
s2 = (1, 3, 5)
# using np.lagsub() method
res = geek.lagsub(s1, s2)
# Resulting laguerre series
print (res)
Output:
[ 1\. 1\. 3.]
代码#2 :
# Python program explaining
# numpy.lagub() 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 = (10, 20, 30, 40, 50)
s2 = (2, 4, 6, 8, 10)
# using np.lagsub() method
res = geek.lagsub(s1, s2)
# Resulting laguerre series
print (res)
Output:
[ 8\. 16\. 24\. 32\. 40.]
