I want to concatenate this "A" matrix vertically. How to do that?I can do that manually. But I want to do it with a loop or in a vectorized way.
A=[1 4 7 10 13 16 19 22 25;
2 5 8 11 14 17 20 23 26;
3 6 9 12 15 18 21 24 27]
output=[A(:,1:3);A(:,4:6);A(:,7:9)] % But I want to do it with a loop or in a vectorized way.
My expected output:
output:[1 4 7;
2 5 8;
3 6 9;
10 13 16;
11 14 17;
12 15 18;
19 22 25;
20 23 26;
21 24 27]

Ran in:
A = [1,4,7,10,13,16,19,22,25;2,5,8,11,14,17,20,23,26;3,6,9,12,15,18,21,24,27]
A = 3×9
1 4 7 10 13 16 19 22 25 2 5 8 11 14 17 20 23 26 3 6 9 12 15 18 21 24 27
B = reshape(permute(reshape(A,3,3,[]),[1,3,2]),[],3)
B = 9×3
1 4 7 2 5 8 3 6 9 10 13 16 11 14 17 12 15 18 19 22 25 20 23 26 21 24 27
