借助**matrix.swapaxes()**方法,我们可以用同样的方法交换矩阵的轴。

语法: matrix.swapaxes() 返回:返回有互换轴的矩阵

示例#1 : 在本例中,我们可以使用matrix.swapaxes()方法交换矩阵的轴。

# import the important module in python
import numpy as np

# make matrix with numpy
gfg = np.matrix('[4, 1; 12, 3]')

# applying matrix.swapaxes() method
geek = gfg.swapaxes(0, 1)

print(geek)

Output:

[[ 4 12]
 [ 1  3]]

例 2 :

# import the important module in python
import numpy as np

# make matrix with numpy
gfg = np.matrix('[4, 1, 9; 12, 3, 1; 4, 5, 6]')

# applying matrix.swapaxes() method
geek = gfg.swapaxes(1, 1)

print(geek)

Output:

[[ 4  1  9]
 [12  3  1]
 [ 4  5  6]]
