Mass-univariate correlation without a loop?

I have to correlate one time-serie with thousands of others. So far im using a loop which looks approximately like this:

for i=1:length(other_timeserie)
  r(i) = corr(my_timeserie,other_timeserie(i))
end

The problem is that it takes forever to run, i was wondering if there was a mass-univariate way to do this without a loop. I thought about using xcorr , but the results is way too big and often create a memory crash.

Nobody? :)

Try without the loop :)

r=corr(my_timeserie,other_timeserie)
