Re: [Haskell-cafe] hmatrix, Windows and GCC
Hi The INSTALL file in the hmatrix repository has some very clear instructions for installation on Windows. http://perception.inf.um.es/~aruiz/darcs/hmatrix/INSTALL However note this section at the bottom: Unfortunately the lapack dll supplied by the R system does not include zgels_, zgelss_, and zgees_, so the functions depending on them (linearSolveLS, linearSolveSVD, and schur for complex data) will produce a non supported in this OS runtime error. Of course linearSolve is exactly what you will be wanting so this won't work for you. I ran into exactly this problem myself. I actually didn't get as far as a run-time error as I got a linker error. I don't have any solution for you though, sorry. regards allan Rafael Gustavo da Cunha Pereira Pinto wrote: Hi all, I am writing a program that uses hmatrix for solving some linear systems.

Re: [Haskell-cafe] hmatrix, Windows and GCC
I was planning to recompile everything (ATLAS, LAPACK and GHC included) this weekend, so I can have a similar environment on Windows and Linux... Having to borrow libraries Since I am married, this means it will actually happen on some weekend till 2010. What I really would like to try is a (purely?) functional approach to create a (P)LU decomposition of a matrix. I am not too much worried (at first) with performance or memory constraints, since I only want to see how beautiful it gets (or not!). (This one might happen somewhere in this century...)

Re: [Haskell-cafe] hmatrix, Windows and GCC
Well, I guess I am not the only one! This blog show exactly what I am looking for! http://quantile95.com/2008/10/31/ann-blas-bindings-for-haskell-version-06/ If you're looking to implement other linear algebra algorithms in Haskell, there's enough at http://github.com/patperry/lapack to implement a QR decomposition with column pivoting with fairly minimal effort. Householder reflections and permutation matrices are already supported. You will also need the latest BLAS bindings, also available at github. Note that these libraries are not compatible with hmatrix. What would *really* be awesome would be an implementation of an SVD algorithm: take a bidiagonal matrix and produce a (lazy) list of Givens rotations that diagonalizes the matrix. That would probably be a 2-4 week project, but would be really useful. Take a look at the code and references at http://netlib.org/lapack/explore-html/zbdsqr.f.html if you're interested. The LAPACK version, zbdsqr, takes B and factors it as B = Q S P^H. Optionally, it sets U := U Q VT := P^H VT C := Q^H C Annoyingly, there is no way to specify an input matrix D and set D := D P. It'd be really cool to have a Haskell function of type svdBidiagonal :: (WriteBanded a m) = a (n,p) e - m [(Givens,Givens)] The type signature means that a is a mutable banded matrix of shape (n,p) with elements of type e that can be modified in monad m. I'm envisioning that the result is a lazy list, gs, and that no computation gets done until the gs list is traversed. So, if someone just wants singular values, then they would do liftM length . svdBidiagonal. If they want to update U := U Q, then they would do something like: mapM_ (applyGivens u) $ liftM (fst . unzip) $ svdDidiagonal a The user has the option to update as many matrices they want in whatever way they want. This is only possible with laziness. It is a perfect example of the glue John Hughes talks about in Why Functional Programming Matters.
