Python Numpy np.polydomain()方法

在np.polydomain()方法的帮助下，我们可以得到具有数组([-1, 1])值的多项式序列的过滤器。

语法 : np.polydomain
返回：返回数组的过滤器([-1, 1])

例子#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]

例子#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]
