Hi list,<br><br>I need to multiply a triangular matrix by a normal (dense) matrix.<br><br>As far as I can tell ublas does not take advantage of the knowledge that (roughly) half the elements of the triangular matrix are zero. I&#39;ve tried prod() and axpy_prod().<br>
<br>Is there a way to do this efficiently with Boot.Ublas or do I have to roll my own product?<br><br>Also, is there a way to detect that a matrix expression will produce a triangular &#39;shape&#39;?<br><br>Thanks in advance!<br>
