Continuous screen output in parfor loop

parfor-print.m

% to enable continuous screen output in a parfor loop place a
% pause of 2-3 seconds before each fprintf or disp statement.
% it seems this flushes the stdout buffer of the worker nodes.
% tested with a local parpool in Matlab R2014b on OS X 10.9.5.
fprintf('pre\n')
parfor n = 1:5
  pause(2)      
  fprintf('start %i\n',n)
  pause(10)
  fprintf('end %i\n',n)
end
pause(2)
fprintf('post\n')
