generates random variates from over 870 univariate distributions

pearson4_cdf(x, m, nu, a, lambda)
% pearson4_cdf.m - evaluates a Cumulative Pearson Type IV Distribution.

function [cdf] = pearson4_cdf(x, m, nu, a, lambda)

for jx = 1:size(x,2)

    elseif(jx == 2)
        cdf(jx) = trapz(x(1:jx),pdf(1:jx));
    elseif(jx > 2)
        cdf(jx) = simps(x(1:jx),pdf(1:jx));
