function y = laprnd(m, n, mu, sigma)
%LAPRND generate i.i.d. laplacian random number drawn from laplacian distribution
% with mean mu and standard deviation sigma.
% mu : mean
% sigma : standard deviation
% [m, n] : the dimension of y.
% Default mu = 0, sigma = 1.

well done

It does what it says. Its vectorized, well coded, with good help, some error checks (ok, it does not check for sigma<0, nor worry about the shapes of its arguments), it has default values for the parameters, an H1 line, a reference to wikipedia. These are all things I like very much to see.

In my obsessive drive for completeness, I'd want to see also tools for the pdf, cdf, and inverse cdf. I wanted to rate this about a 4.5 as is.
