Hackage :: [Package]

matrix-sized: Haskell matrix library with interface to C++ linear algebra libraries.

[ bsd3, library, math ] [ Propose Tags ] [ Report a vulnerability ]

A Haskell implementation of matrices with statically known sizes. The library also comes with the bindings to high performance C++ linear algebra libraries such as Eigen and Spectra.

Readme for matrix-sized-0.0.2

[back to package description]

Type-safe linear algebra library

  • General matrix types are implemented in native Haskell.

  • The dimensions of matrices are statically typed.

  • Provides bindings to high performance C++ linear algebra libraries such Eigen and Spectra.

Following GHC extensions may be needed:

  • ScopedTypeVariables
  • RankNTypes
  • TypeFamilies
  • DataKinds

Example

let mat = D.matrix [ [1,0,3]
                   , [0,5,6]
                   , [0,0,0] ] :: Matrix 3 3 Double
    mat' = D.convertAny mat :: SparseMatrix 3 3 Double

print mat
print mat'

print $ eigs (sing :: Sing 1) mat == eigs (sing :: Sing 1) mat'

print $ cholesky mat

print $ mat %*% mat %*% mat
print $ mat' %*% mat' %*% mat
