Data.Elem.BLAS

Type classes for elements with BLAS support.

Base element type class

class (AEq e, Storable e, Fractional e) => Elem e where

The base class for elements.

Methods

conjugate :: e -> e

Get the complex conjugate of a value.

norm :: e -> Double

Get the magnitude of a value.

norm1 :: e -> Double

Get the l1 norm of a value.

fromReal :: Double -> e

Convert a double to an element.

maybeToReal :: e -> Maybe Double

Try to coerce a value to a double. This will fail unless the complex part is zero (according to a comparison by (~==)).

Instances

Elem Double

Elem (Complex Double)

BLAS element types

class Elem a => BLAS1 a

Types with vector-vector operations.

Instances

BLAS1 Double

BLAS1 (Complex Double)

class BLAS1 a => BLAS2 a

Types with matrix-vector operations.

Instances

BLAS2 Double

BLAS2 (Complex Double)

class BLAS2 a => BLAS3 a

Types with matrix-matrix operations.

Instances
