Moving columns below other columns, in a matrix
Hi everyone!
Say I have a 6x6 matrix - what is the easiest way of moving the rightmost 3 columns below the leftmost 3 columns, such that the matrix becomes 12x3?
Thanks for any help!

A =3D magic(6);
B =3D [A(:,1:3);A(:,4:6)]
or:
B =3D [reshape(A(:,1:3:end),[],1) reshape(A(:,2:3:end),[],1) reshape(A(:,
3:3:end),[],1)]

Easiest:
[C(:,1:3);C(:,4:6)];
More generally:
[C(:,1:end/2);C(:,end/2+1:end)]
