借助**Numpy matrix.reshape()**方法,我们能够重塑给定矩阵的形状。请记住,在对给定矩阵进行整形后,所有元素都应该被覆盖。

语法: matrix.reshape(shape)

回归: 新换阵

示例#1 : 在给定的示例中,我们能够使用matrix.reshape()方法重塑给定的矩阵。

# import the important module in python
import numpy as np

# make matrix with numpy
gfg = np.matrix('[64, 1; 12, 3]')

# applying matrix.reshape() method
geeks = gfg.reshape((1, 4))

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; 4, 5; 7, 8]')

# applying matrix.reshape() method
geeks = gfg.reshape((2, 3))

print(geeks)

Output:

[[1 2 4]
 [5 7 8]]
