I was looking for a way to solve a linear system using ublas and came upon this thread

So does this mean I have to decompose my matrix? Can I do it using ublas?
Well ... yes and no ;o) ublas is BLAS (i.e. Basic Linear Algebra Subroutines) written in C++, so it provides (only) elementary vector and matrix operation (scaling, addition, matrix/vector and matrix/matrix multiplication etc.). But we are developing `bindings' library which provides interfaces to some Fortran and C numeric libraries, e.g. ATLAS and LAPACK, so that they can be used with ublas matrices and vectors. Current version of `bindings' library (not complete, but IMHO useable) can be found in the boost sandbox http://tinyurl.com/r1ch with documentation and examples in http://tinyurl.com/r1cv You can also download complete zip archive from the files section of the ublas-dev mailing list http://groups.yahoo.com/group/ublas-dev/files/ (I think that you must join the mailing list to access the files: ublas-dev-subscribe@yahoogroups.com .)
