function p = dglnpdf(n,alpha,beta)
%DGLNPDF Discrete generalized log-normal probability density function.
%
%   P = DGLNPDF(N,ALPHA,BETA) returns the probabilities for a discrete
%   version of the generalized log-normal probability density function. In
%   this case, Prob(x) ~ exp(-(log(x)/alpha)^beta) for x = 1:N.
