ublas compatible solvers (newbie question) (Zrubavel Zodikovich)
------------------------------ Message: 2 Date: Fri, 05 Nov 2004 22:52:14 +0200 From: Zrubavel Zodikovich <g729@mail.com> Subject: [Boost-users] ublas compatible solvers (newbie question) To: boost-users@lists.boost.org Message-ID: <cmgosk$jst$1@sea.gmane.org> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Hi all, I'm looking into using uBLAS for solving some big sparse systems, specifically with conjugate gradient family of solvers. Could anyone point me towards boost-compatible implementation of such solver ? thanks in advance ------------------------------ Hello, I know of no such solvers in or out of uBLAS so I am not of much help. However, you may want to consider interfacing uBLAS with libraries which are not compatable with uBLAS. You will find such interfaces in the BOOST-sandbox CVS. I may be undertaking a similar exercise between uBLAS and some sparse system solvers. Also, there exists documentation for these bindings, but I cannot find the link :( Best of luck, Dan

Interesting. Do you have any specific ones in mind? I took a look at LASPACK, but unfortunately it doesn't appear to use BLAS. Obviously, not reinventing the wheel would be best. Cheers, Andrew Bromage
Have anyone ever thought about implementing bindings for the PETSc library? To me, PETSc (http://www-unix.mcs.anl.gov/petsc/petsc-2/) seems to be the best numeric library so far. Cheers, Lorenzo. On Tue, 2004-11-09 at 00:30, ajb@spamcop.net wrote:

Is it true that new documentation is being created for uBLAS? Will this be released with 1.32? Will it contain additional information about sparse matrix types?
