contains some
% information about the run and a matrix outputs |chain| and
% |s2chain| that contain the actual MCMC chains for the parameters
% and for the observation error variance.

%%
% The |chain| variable is |nsimu| × |npar| matrix and it can be
% plotted and manipulated with standard Matlab functions. MCMC toolbox
% function |mcmcplot| can be used to make some useful chain plots and
% also to plot 1 and 2 dimensional marginal kernel density estimates of
% the posterior distributions.
