Could someone have a
look at the lines for setting the priors for correlation in
set_prior.m (occurring in at least two places):
ub = [ub;
max(min(estim_params_.corrx(:,5),1),-1)];
lb = [lb;
max(min(estim_params_.corrx(:,4),1),-1)];
In case
estim_params_.corrx(:,4) is NaN, the lower bound defaults to
+1 instead of -1.
