借助Numpy matrix.diagonal()
方法,我們能夠找到一個diagonal element
從給定的矩陣中得出並以一維矩陣形式輸出。
用法: matrix.diagonal()
返回: 返回矩陣的對角線元素
範例1:
在此示例中,我們可以借助matrix.diagonal()
方法,我們能夠找到矩陣對角線中的元素。
# import the important module in python
import numpy as np
# make matrix with numpy
gfg = np.matrix('[6, 2; 3, 4]')
# applying matrix.diagonal() method
geeks = gfg.diagonal()
print(geeks)
輸出:
[[6 4]]
範例2:
# import the important module in python
import numpy as np
# make a matrix with numpy
gfg = np.matrix('[1, 2, 3; 4, 5, 6; 7, 8, 9]')
# applying matrix.diagonal() method
geeks = gfg.diagonal()
print(geeks)
輸出:
[[1 5 9]]
