Python| numpy matrix.argmax()
借助Numpy matrix.argmax()
方法,我们能够找到给定矩阵中具有一维或多维的最大元素的索引值。
Syntax : matrix.argmax()
Return : Return index number of maximum element in matrix
示例 #1:
在这个例子中,我们可以看到在matrix.argmax()
方法的帮助下,我们能够找到给定矩阵中最大元素的索引。
# import the important module in python
import numpy as np
# make a matrix with numpy
gfg = np.matrix('[1, 2, 3, 4]')
# applying matrix.argmax() method
geeks = gfg.argmax()
print(geeks)
输出:
3
示例 #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.argmax() method
geeks = gfg.argmax()
print(geeks)
输出:
8
