借助**Numpy matrix.ravel()**
方法,我们可以从给定的矩阵中得到展平的矩阵。
语法:
matrix.ravel()
返回: 从给定矩阵返回扁平矩阵
示例#1 :
在这个示例中,我们可以看到,借助方法matrix.ravel()
,我们能够从给定的矩阵中获得展平的矩阵。
# import the important module in python
import numpy as np
# make matrix with numpy
gfg = np.matrix('[64, 1; 12, 3]')
# applying matrix.ravel() method
geeks = gfg.ravel()
print(geeks)
Output:
[[64 1 12 3]]
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.ravel() method
geeks = gfg.ravel()
print(geeks)
Output:
[[ 1 2 3 4 5 6 7 8 -9]]
