 weights between the observation sites and each other. It should be a 3D array with one row and one column per observation site. Each element along the third dimension of yloc must be a symmetric matrix.</p>
<p>The two inputs must have the same number of elements along the third dimension. If the third dimension has one element (i.e. both inputs are matrices), then uses the same localization weights in all time steps. Otherwise, the third dimension must have one element per time step (although see the next
