&gt; have you tried to define <br />&gt; BOOST_UBLAS_ENABLE_PROXY_SHORTCUTS ? <br /><br />Worked.  That was what I was missing, thanks.  Is there any page which is a good guide to all of the preprocessor settings?<br /><br />Also, any ideas on a good generic concept for working with ublas::matrix, c 2D array, multi_array&lt;Real, 2&gt; ?
