-
-
vector
An efficient implementation of Int-indexed arrays (both mutable and immutable), with a powerful loop optimisation framework . -

-
hgeometry
HGeometry is a library for computing with geometric objects in Haskell. It defines basic geometric types and primitives, and it implements some geometric data structures and algorithms. The main two focusses are: (1) Strong type safety, and (2) implementations of geometric algorithms and data structures that have good asymptotic running time guarantees. -
dimensional
Dimensional library variant built on Data Kinds, Closed Type Families, TypeNats (GHC 7.8+). -

-
numhask
A haskell numeric prelude, providing a clean structure for numbers and operations that combine them. -
-
poly
Fast polynomial arithmetic in Haskell (dense and sparse, univariate and multivariate, usual and Laurent) -
-
-
eigen
Haskel binding for Eigen library. Eigen is a C++ template library for linear algebra: matrices, vectors, numerical solvers, and related algorithms.

About hblas
hblas is an open source component of the Wellposed® mathematical software suite.
Members of the numerical haskell open source community can be found on irc at #numerical-haskell on freenode,
and via the numericalhaskell mailing list.
hblas is a self contained full (well, not quite yet) BLAS and LAPACK binding that provides the full BLAS and LAPACKE APIs in a simple, unopinionated, Haskell wrapper.
This library is NOT meant to be used by end users, it is designed to be an unopinionated, simple, portable, easy to install BLAS/LAPACK substrate for higher level numerical computing libraries to build upon. Morever, this library is strictly a wrapper, and simply makes using the functionality of BLAS and LAPACK more accessible.
This library is NOT meant to be used a standalone array library (except in desperation), but rather should be used by a higher level numerical array library to provide high performance linear algebra routines.
Install
By default, hblas will assume you have BLAS and LAPACK built and installed.
OSX
On OS X systems, things will just work.
$ cabal install
Linux
On linux and bsd systems, you will need to manually install the BLAS and LAPACK libraries beforehand.
$ sudo apt-get install libblas liblapack
$ cabal install
Testing
To run the test suite execute:
$ cabal test
Linking
If you get an error like undefined reference to 'cblas_sdsdot' when building or running an HBLAS program,
you might be on a system that builds BLAS and CBLAS separately, such as Arch Linux.
In which case, be sure to install CBLAS and invoke cabal install hblas -fCBLAS
to make sure hblas links to CBLAS properly.
Usage
API is subject to change.
import Foreign.Storable
import Numerical.HBLAS.BLAS
import Numerical.HBLAS.MatrixTypes
-- Generate the constant mutable square matrix of the given type and dimensions.
constMatrix :: Storable a => Int -> a -> IO (IODenseMatrix Row a)
constMatrix n k = generateMutableDenseMatrix SRow (n,n) (const k)
example_dgemm :: IO ()
example_dgemm = do

right <- constMatrix 2 (3 :: Double)
out <- constMatrix 2 (0 :: Double)
