关于numpy.maximum函数的测试

atr.py

import numpy as np

a = np.arange(9)
print("a:",a)
print(a[0:3])
print(a[3:6])
print(a[6:9])
print("testj:" ,np.maximum(a[0:3], a[6:9],a[3:6]))
print(a[0:3])
print(a[3:6])
print(a[6:9])

-----------------------
输入结果：

a: [0 1 2 3 4 5 6 7 8]
[0 1 2]
[3 4 5]
[6 7 8]
testj: [6 7 8]
[0 1 2]
[6 7 8]
[6 7 8]

print("testj:" ,np.maximum(a[0:3],a[3:6],a[6:9]))
print(a[0:3])

print(a[3:6])
print(a[6:9])

输入结果：

a: [0 1 2 3 4 5 6 7 8]
[0 1 2]
[3 4 5]
[6 7 8]
testj: [3 4 5]
[0 1 2]
[3 4 5]
[3 4 5]

最后print(“a:”a)
结果a: [0 1 2 3 4 5 3 4 5]
