Hi, I have a matrix, which I need to sort in two group: First group: Pick first 5 rows (and all columns) and leave next five rows and again pick another five, leave next five and so on. Second group: Pick only those which were not selected in first group.
Thanks in advance.

As follow-up to previous question, how do I get the average value (mean) of each of those picked 5 rows?
Thanks

Example
A=rand(20,6);
idx=reshape(1:size(A,1),5,[]);
m=size(idx,2);
idx1=idx(:,1:2:end);
idx2=idx(:,2:2:end);
A1=A(idx1(:),:)
A2=A(idx2(:),:)
