Numpy Python transpose() 矩阵转置

Numpy numpy.transpose(),可以实现矩阵的转置。

也可以输入参数，实现行与列的转置

# making a 3x3 array
a = np.array([[1, 2],
                [4, 5],
                [7, 8]])
  
# before transpose
print(a, end ='\n\n')
  
# after transpose
print(a.transpose(1, 0))

//output
[[1 2]
 [4 5]
 [7 8]]

[[1 4 7]
 [2 5 8]]
