借助**Numpy matrix.tostring()**方法，我们可以使用matrix.tostring()方法为矩阵找到字符串格式的字节码。
语法:
matrix.tostring()返回: 返回矩阵的字节码串
示例#1 :
在这个示例中，我们可以看到，通过使用**matrix.tostring()**方法，我们能够找到给定矩阵的字符串格式的字节代码。
# import the important module in python
import numpy as np
# make matrix with numpy
gfg = np.matrix('[4, 1; 12, 3]')
# applying matrix.tostring() method
geek = gfg.tostring()
print(geek)
Output:
b ' \ x04 \ x00 \ x00 \ x00 \ x00 \ x00 \ x01 \ x00 \ x00 \ x00 \ x00 \ x00 \ x00 \ x0c \ x00 \ x00 \ x00 \ x00 \ x00 \ x03 \ x00 \ x00 \ x00 \ x00 \ x00 \ x00′
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.tostring() method
geek = gfg.tostring()
print(geek)
Output:
b ' \ p04 \ x000 \ x000 \ x000 \ x000 \ x000 \ x000 \ x000 \ x000 \ x000 \ 0x 00 \ 0x 00 \ t0c \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 00 \ 0x 01 \ x 01 \ n
