MATLAB: Using normrnd to generate a random sequence

Question

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?

Answer 1

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.
