*sigh* Why is everyone always obsessed with doing everything in one command?
Writing two commands to achieve your goal isn't the end of the world, is it?

% generate sample data
A = reshape(1:12, 2, 6).';

% The engine
b1 = reshape(A, 3, 4);
b = [b1(:, 1:2:end) b1(:, 2:2:end)]

Perhaps aiming for the Zen of a zero line command?

It's Matlab's fault for trying to provide syntax and functions to do anything imaginable in one command! ;-)
