I guess best thing to get pure random number is use time function. Try to
get cpu clock cycle and it is going to be random, than reminder it from maximum
allow able length... wht u suggest
some time C / matlab repeats same series of numbers.

Its not that the
function you are using is not producing random number with mean near zero.
Its just that you are using very few samples. Try increasing the
number of samples and you will see mean converge to zero.
If you
use rand() function you will get similar result.
Just a suggestion,
to make use of matlab's intrinsic matrix processing capability and to
reduce use of for loop you can get same result's using
a =
unifrnd (-2 , 2 , [1024,1]); Hope this helps Tarang
