Please format your code and explain what is the grouping.

Pat, please try to imagine yourself as a reader who knows nothing about your problem. It is impossible to understand what you want to do. Please provide more detail.

@Pat: As mentioned before, it is not clear how the groups are distinguished. I do not see the connection between "The values in the column 1 and 2 should not change" and the example data in your question. Please explain the rule you want to implement.
But you've accepted an answer already. This means, that the posted code solved your problem. Sure?

b=mat2cell(a,repmat(2,size(a,1)/2,1),size(a,2));
c=cell2mat(b');

@Fangjun: Pat asks for 5 groups, but he showed 6 groups. Your code replies a {2 x 10} cell.

I see! Then b or b' should be the outcome.
The OP doesn't seem to be responsive at all based on his history.
