from numpy.polynomial.polynomial import polyone
# using np.polyone() method
ans = polyone
print(ans)
输出:
[1]
例 2 :
# Python program explaining
# numpy.polyone() method
# import numpy and polyone
import numpy as np
from numpy.polynomial.polynomial import polyone
# using np.polyone() method
ans = polyone + [[1, 3, 5], [2, 4, 6]]
print(ans)
输出:
[[2 4 6] [3 5 7]]
