Python| Numpy np.polydomain() 方法
借助np.polydomain()方法，我们可以得到具有多项式级数数组 ([-1, 1])值的过滤器。
Syntax : np.polydomain
Return : Return filter of array([-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]
示例 #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]
