Hello,
I have a NxM matrix:
Random A for example 10x5
A =
2 8 7 1 4
9 8 8 1 7
4 8 2 8 8
3 3 2 10 6
8 7 6 7 8
1 6 5 2 3
1 4 9 8 8
7 1 8 2 10
7 8 8 2 9
6 4 1 7 1
I would like to make another matrix (B) that contains first every N, N+2, N+4...and after them N+1,N+3.. ect
B =
2 8 7 1 4
4 8 2 8 8
8 7 6 7 8
1 4 9 8 8
7 8 8 2 9
9 8 8 1 7
3 3 2 10 6
1 6 5 2 3
7 1 8 2 10
6 4 1 7 1
Thank you.

Note that this is a topic of indexing/rearranging the elements, where the element values are not relevant to the new order (only their indices are). Sorting depends only on the element values (not their indices).
