Python | Numpy np.polydomain()方法

原文:https://www . geesforgeks . org/python-numpy-NP-poly domain-method/

借助**np.polydomain()**方法,我们可以得到多项式级数形式的具有值数组([-1,1]) 的滤波器。

语法: np.polydomain 返回:返回数组的过滤器([-1,1])

示例#1 :

# Python program explaining
# numpy.polydomain() method 

# import numpy and polydomain
import numpy as np
from numpy.polynomial.polynomial import polydomain

# using np.polydomain() method
for i in range(5):
    ans = polydomain + [i, i + 1]
    print(ans)

输出:

[-1 2] 【0 3】 【1 4】 【2 5】 【3 6】

例 2 :

# Python program explaining
# numpy.polydomain() method 

# import numpy and polydomain
import numpy as np
from numpy.polynomial.polynomial import polydomain

# using np.polydomain() method
for i in range(4):
    ans = polydomain + [i-1, i + 1]
    print(ans)

输出:

[-2 2] [-1 3] [0 4] [1 5]
