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?

Vectorize. It's clearer.
