Answer 1

[Tom]

a = reshape(1:9,3,3)';

a = a(:)'

Answer 2

[John D'Errico]

Yes, @Tom has given a great answer. The way I would solve it on any normal day. But, just perhaps, is there another way? There always is...

ind = 0:8;
1 + 3*mod(ind,3) + floor(ind/3)

ans = 1×9

1 4 7 2 5 8 3 6 9

Look carefully at how it works. Take apart each piece.
