# import the important module in python
import numpy as np
# make matrix with numpy
gfg = np.matrix('[64, 1; 12, 3]')
# applying matrix.mean() method
geeks = gfg.mean()
print(geeks)
输出:
20.0
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.mean() method
geeks = gfg.mean()
