Laplacian random number generator

Generate i.i.d. random number drawn from laplacian distribution with specified parameter

Description

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.
% For more information, refer to

• Required Products: Statistics Toolbox
• MATLAB release: MATLAB 7.1.0 (R14SP3)

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.
