Thread Subject: sampling without repetition

Hi, I need to sample randomly (unified) without repetition out of a vector.
I know the function randperm(), the catch is that the vector is huge and not really on my memory, I need a function that'll generate only m<<n integers in the range of 1:n

I'm confused.
Should I reply to this new thread that you have started, or the old
one here:
http://groups.google.com/group/comp.soft-sys.matlab/browse_thread/thread/1a6ea42d5d4bb901/bf3c6310aaffbd9e#bf3c6310aaffbd9e

And why didn't you explain in the original thread what it was you
actually wanted?
Are you purposely obfuscating? If so, why?
