Python| numpy matrix.reshape()
在Numpy matrix.reshape()
方法的帮助下,我们能够重塑给定矩阵的形状。请记住,在重塑给定矩阵后应覆盖所有元素。
Syntax : matrix.reshape(shape)
Return: new reshapped matrix
示例 #1:
在给定的示例中,我们可以使用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)
输出:
[[64 1 12 3]]
示例 #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)
输出:
[[1 2 4]
[5 7 8]]
