借助Numpy matrix.argmax()
方法,我們能夠在給定的具有一維或多維維度的矩陣中找到最小元素的索引值。
用法: matrix.argmin()
返回: 返回矩陣中最小元素的索引數
範例1:
在此示例中,我們可以借助matrix.argmax()
方法,我們能夠找到給定矩陣中最小元素的索引。
# import the important module in python
import numpy as np
# make a matrix with numpy
gfg = np.matrix('[1, 2, 3, 4]')
# applying matrix.argmin() method
geeks = gfg.argmin()
print(geeks)
輸出:
0
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.argmin() method
geeks = gfg.argmin()
print(geeks)
輸出:
4
