Python| numpy matrix.repeat()

借助Numpy matrix.repeat()方法,我们可以从给定矩阵中获取重复值,并将输出作为一维数组。

示例 #1:
在这个例子中,我们可以看到我们能够在方法matrix.repeat()的帮助下从给定矩阵中获取重复值。

# import the important module in python
import numpy as np
          
# make matrix with numpy
gfg = np.matrix('[64, 1; 12, 3]')
          
# applying matrix.repeat() method
geeks = gfg.repeat(2)
    
print(geeks)
输出:
[[64 64  1  1 12 12  3  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.repeat() method
geeks = gfg.repeat(3)
    
print(geeks)
输出:
[[ 1  1  1  2  2  2  3  3  3  4  4  4  5  5  5  6  6  6  7  7  7  8  8  8
  -9 -9 -9]]
