You said till the end, what is the end in your case. And what is your array? a cell array? or what?

One of many many ways to do this:

m = randi(9, 184, 32)
[rows, columns] = size(m);
for row = 1 : 16 : rows
  fprintf('\nRows %d - %d\n', row, row+7);
  fprintf('%d, ', m(row,:));
  fprintf('\n');
  fprintf('%d, ', m(row+1,:));
  fprintf('\n');
  fprintf('%d, ', m(row+2,:));
  fprintf('\n');
  fprintf('%d, ', m(row+3,:));
  fprintf('\n');
  fprintf('%d, ', m(row+4,:));
  fprintf('\n');
  fprintf('%d, ', m(row+5,:));
  fprintf('\n');
  fprintf('%d, ', m(row+6,:));
  fprintf('\n');
  fprintf('%d, ', m(row+7,:));
end
