move rows in a matrix

Guys, I have a Matrix X= [A; B; C; D ; E; a; b; c; d; e ; f] each alphabet represents a row matrix with three columns. I want a Matrix X= [ A; a; b; c; B; d; e; f; C; D; E]. How to do it??

Use MATLAB's rather powerful indexing ability:

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