could anyone help me how to pair the numbers in the desired manner as shown below

1 回表示 (過去 30 日間)
A=1:16
R = reshape(A,4,[])
After executing the above command results in
R =
1 5 9 13
2 6 10 14
3 7 11 15
4 8 12 16
Now I want to group the numbers in the desired manner
1 2 3 4 5 6 7 8
12 11 10 9 16 15 14 13
Could anyone please help me on this.

This looks a quite a unique manner. Anyways, try this
A=1:16;
R = reshape(A,4,[]);
[R(:,1)' R(:,2)'; flip(R(:,3))' flip(R(:,4))']
ans = 2×8
1 2 3 4 5 6 7 8 12 11 10 9 16 15 14 13

I am not sure what you mean by combining all into a single code, so here's my approach -
for i=[3 4 6 9 12]
z=1:4*i;
y=reshape(z,[],4);
R=[y(:,1)' y(:,2)'; flip(y(:,3))' flip(y(:,4))']
end
R = 2×6
1 2 3 4 5 6 9 8 7 12 11 10
R = 2×8
1 2 3 4 5 6 7 8 12 11 10 9 16 15 14 13
R = 2×12
1 2 3 4 5 6 7 8 9 10 11 12 18 17 16 15 14 13 24 23 22 21 20 19
R = 2×18
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 27 26 25 24 23 22 21 20 19 36 35 34 33 32 31 30 29 28
R = 2×24
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 36 35 34 33 32 31 30 29 28 27 26 25 48 47 46 45 44 43 42 41 40 39 38 37
Here R will be modified in each iteration. You can modify the code according to however you want to proceed.

reshape(A, 8, 2)'

This doesn't give the correct output

Whoops. Didn't pay attention to the order of the second row.
Then we need to use flip most likely.
A=1:16
R = reshape(A,4,[]);
R(:, 3) = flip(R(:, 3));
R(:, 4) = flip(R(:, 4));
ret = reshape(R, 8, 2)'
