function s = random_sample(cnts, nsamples)

%RANDOM_SAMPLE creates a random sample proportional to the given counts. % % S = RANDOM_SAMPLE(C) choose N = round(sum(C)) samples (with % replacement) from {1,...,length(C)} proportional to the values in C. % So, if C = [2 1 1], then we might expect S (sorted) to be [ 1 1 2 3 ]. % However, we also allow for C to be non-integral. % % Tamara G.
