I'm trying to use the function 'normrnd' to generate a zero-mean random sequence distributed uniformly between +/- 0.25. How do I go about doing this?

The best answer to your question is, “don’t use ‘normrnd’ for that purpose!” It is very much the wrong distribution for that.
You should use ‘rand’ as follows:
x = 0.5*rand(m,n)-0.25;
This will give you a statistically uniform distribution between -0.25 and +0.25, and nowhere else.

Hi Nat
.. to generate a .. random sequence ..
x = 0.5*rand(1,n)-0.25
or
x = 0.5*rand(n,1)-0.25
not m sequences
