Reshape 读取和摆放顺序: Matlab VS Python

1. Matlab读取：列优先(高维矩阵：靠前的维度优先)

>> b = [1,2;3,4];
>> reshape(b,1,4)

ans =

     1     3     2     4

2. Matalb填充：列优先(高维矩阵：靠前的维度优先)

>> b = [1      2      3      4]

b =

     1     2     3     4

>> reshape(b,2,2)

ans =

     1     3
     2     4

3. Python读取：行优先(高维矩阵：靠后的维度优先)

import numpy as np
a = np.array([[1,2],[3,4]])
b = np.reshape(a,(1,4))
print(b)

[[1 2 3 4]]

4. Python填充：行优先(高维矩阵：靠后的维度优先)

import numpy as np
a = np.array([1,2,3,4])
b = np.reshape(a,(2,2))
print(b)

[[1 2]
 [3 4]]

这都是默认情况，Python通过传参'C' or 'F'还是能改变顺序的。
值得一提的是，对于Matlab，没有传参改变填充顺序的机会，只能通过矩阵转置来处理。
