ix outputs <tt>chain</tt> and <tt>s2chain</tt> that contain the actual MCMC chains for the parameters and for the observation error variance.</p><p>The <tt>chain</tt> variable is <tt>nsimu</tt> &times; <tt>npar</tt> matrix and it can be plotted and manipulated with standard Matlab functions. MCMC toolbox function <tt>mcmcplot</tt> 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.</p><pre class="codeinput">figure
