MATLAB: Move matrix rows and columns

move matrix rows and columnsreshape

I have a n*n matrix. I want to convert it to n^2*1 matrix. for example: A=[a b;c d] result B=[a;b;c;d]

B=reshape(A.',[],1);

If you want to preserve each 4x3 block, you could try something like this:

B = reshape(A(:, [1:3:end, 2:3:end, 3:3:end]), [], 3 );

Use MATLAB's rather powerful indexing ability:

 X = [...];
 X = X([1,6,7,8,2,9,10,11,3,4,5],:);
