Eliminating a for loop for faster computation

HI, FInd below part of my code .Is it possible to substitute the for loop so that it is faster and takes less computation?

 time_durations=zeros(length(out),1)';
 for k=1:length(out)
 time_durations(k)=minutes(time_select_20000(out(k,3))-time_select_20000(out(k,2)));     
 end

Have you tried

minutes(time_select_20000(out(:,3))-time_select_20000(out(:,2)))

with no loop?

Yes it works! Based on your experience, in this particular case, which one would you suggest?

Vectorize. It's clearer.
