Python| numpy matrix.std()
借助matrix.std()
方法,我们可以使用相同的方法找到矩阵的标准差。
Syntax : matrix.std()
Return : Return standard deviation of a matrix
示例 #1:
在此示例中,我们可以使用matrix.std()
方法找到矩阵的标准差。
# import the important module in python
import numpy as np
# make matrix with numpy
gfg = np.matrix('[4, 1; 12, 3]')
# applying matrix.std() method
geek = gfg.std()
print(geek)
输出:
4.18330013267
示例 #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.std() method
geek = gfg.std()
print(geek)
输出:
3.3993463424
