Reshape MATLAB vector in Row-wise manner

Say I have a matrix a = [1 2 3 4 5 6];, how do I reshape it in a row-wise manner for example reshape(a, 2, 3) to yield

1 2 3 
4 5 6

rather than the default column-wise result produced by MATLAB of:

1 3 5 
2 4 6

I believe this is a trivial task which probably has an inbuilt function to achieve this. I have already implemented a function that does this perfectly... however, is there a shorter, neater and more MATLAB way? Thanks.

function y = reshape2(x, m, n) 
  y = zeros(m, n);

  ix = 0; 
  for i = 1:m
     for j = 1:n
         ix = ix + 1;
         y(i, j) = x(ix);
     end 
  end 
end
