They include <A HREF="dense.html" >dense</A>, <A HREF="packed.html" >packed</A>, <A HREF="banded.html" >banded</A>, and <A HREF="banded_view.html" >banded_view</A>. The common theme here is that the <A HREF="matrix.html" >matrix</A> is stored in a contiguous piece of memory. The differences in these storage types has to do with where to find the OneD segements in the linear memory. Caclulating these offsets is the job of the <A HREF="Offset.html" >Offset</A> concept, which has a model to handle each of the different storage types: <A HREF="rect_offset.html" >rect_offset</A>, <A HREF="strided_offset.html" >strided_offset</A>, <A HREF="banded_offset.html" >banded_offset</A>, <A HREF="packed_offset.html" >packed_offset</A>, and <A HREF="banded_view_offset.html" >banded_view_offset</A>. There are two derived classes of <A HREF="generic_dense2D.html" >generic_dense2D</A> that specify the memory management, <A HREF="dense2D.html" >dense2D</A> and <A HREF="external2D.html" >external2D</A>. The <A HREF="dense2D.html" >dense2D</A> version owns its memory, while the <A HREF="external2D.html" >external2D</A> imports its memory from somewhere else through a pointer (which allows for interoperability with other codes -- even with Fortran!). <p>JGS Nasty VC workaround VC doesn't like thisfriend class transpose_type;</TD></TR><TR><TD><IMG SRC="whitespace.gif" Alt="" WIDTH="32"
