MATLAB: How to retrieve Matrix every three numbers

Question

A = randi(10,10,5);
A =
     2     8     7     1     4
     9     8     8     1     7
     4     8     2     8     8
     3     3     2    10     6

     6     4     1     7     1

In this case how can i retrieve in for loop

1. 2, 8
2. 7, 1
3. 4

Thanks

Answer 1

nc = size(A,2);
for K = 1 : 2 : nc
  if K == nc
     result = A(1,K);
  else
     result = A(1, K:K+1);
  end
end
