Great, helps much, that is something I was hoping for :). As for now, we can generate matrix in-order. In the future it seems we will need to generate matrix in "transposed" order, e.g. row-by-row order for the lower triangular part. But then I suppose we will need to use MatMultTranspose() or MatCreateTranspose() if the performance won't suffer much (I have not tried it yet, so I have no idea about it for now.)</blockquote>
