[Q] How to get the fastest speed ?

Hi everyone,

I have a question about Matlab speed. Is it always true that
a vectorized code is always faster than non-vectorized code
(using for loop or while loop) ?

For example in simulating a communications system, we can
create a very long vector (say 1e6 elements) and prcoess this
long vector once. On the other hand, we can also create 10 short
vectors (say 1e5 elements) and repeat the same processings on the
10 vectors.

So which method results in a faster code ?


Thanks for your help !!!
