Python:Numpy 求平均向量的实例

如下所示：

>>> import numpy as np
>>> a = np.array([[1, 2, 3], [3, 1, 2]])
>>> b = np.array([[5, 2, 6], [5, 1, 2]])
>>> a
array([[1, 2, 3],
   [3, 1, 2]])
>>> b
array([[5, 2, 6],
   [5, 1, 2]])
>>> c = a + b
>>> c
array([[6, 4, 9],
   [8, 2, 4]])
>>> c = (a+b)/2
>>> c
array([[ 3. , 2. , 4.5],
   [ 4. , 1. , 2. ]])
>>>
