How to reshape a matrix?

1 次查看(过去 30 天)
Suppose I have a 2D matrix (6,3) as follows
A
1 2 3
4 5 6
7 8 9
10 11 12
13 14 15
16 17 18
Now I want to reshape into one 3D matrix (3,3,2) like as follows:
A_3D(:, :, 1)
1 2 3
4 5 6
7 8 9
A_3D(:, :, 2)
10 11 12
13 14 15
16 17 18
How I can achieve that with an efficient way?
Thank you

Combination of reshape and permute
permute(reshape(A, 3, size(A,1)/3, []), [1 3 2])

It is working fine. Now I have to understand the logic behind this line of code. Thank you very much.
