generates random variates from over 870 univariate distributions

normmom_pdf(x, alpha)
% normmom_pdf.m - evaluates a Normal Moment Probability Density.
%   See "On the Normal Moment Distributions", A. Olosunde,
%   Vector form of PDF!

function [pdf] = normmom_pdf(x, alpha)

%persistent coef

    coef = exp(-(alpha+0.5)*log(2) - gammaln(alpha+0.5));

pdf = coef .* (abs(x)).^(2*alpha) .* exp(-0.5.*(x.^2));
