 b=[0,1,0,0,0,0,0,1,0,1,0,0,0,0,0,1,0,1,0,0,0,0,0,1,0,1,0,0,0,0,0,1];
>> SS=reshape(b,length(b)/8,8);
>> SS

SS =

   0     0     0     0     0     0     0
   0     1     0     1     0     1     0
   0     0     0     0     0     0     0
   1     0     1     0     1     0     1

bt i want to get

SS =

   1     0     0     0     0     1     0
   1     0     0     0     0     1     0

Where does the trailing zero column come from? It is not clear why the last and teh 2nd last column seem to have swapped.
