I need to write my own random number generator function that has no seed and is unpredictable. if anyone know about the algorithms or source code of MATLAB rand() function please let me know. any help in this regard will really be appreciated.ASAP
I have tried generating through system clock but it is not efficient.
Thanks Safiullah

I just read about this in Wired Magazine. Here's the article; good luck - I think you'll need it!

FWIW, MATLAB's random number generators require a seed and are deterministic given the seed.

You will find very specific literature references to all of the generators that MATLAB provides if you look in the MATLAB documentation:
