The NORTA method implemented via simdesign_norta() requires a one time setup to compute the initial correlations for the normal distributions which are then transformed to the final marginals. This setup requires naively p(p-1) univariate optimization problems (where p is the number of desired variables), resulting in a quadratic scaling behaviour.
