Description

Generic interface to Blas using safe foreign calls. Refer to the GHC documentation for more information regarding appropriate use of safe and unsafe foreign calls.

The functions here are named in a similar fashion to the original Blas interface, with the type-dependent letter(s) removed. Some functions have been merged with others to allow the interface to work on both real and complex numbers. If you can't a particular function, try looking for its corresponding complex equivalent (e.g. symv is a special case of hemv applied to real numbers).

Note: although complex versions of rot and rotg exist in many implementations, they are not part of the official Blas standard and therefore not included here. If you really need them, submit a ticket so we can try to come up with a solution.

The documentation here is still incomplete. Consult the official documentation for more information.

Notation:

⋅ denotes dot product (without any conjugation).
* denotes complex conjugation.
⊤ denotes transpose.
† denotes conjugate transpose (Hermitian conjugate).

Conventions:

All scalars are denoted with lowercase Greek letters
All vectors are denoted with lowercase Latin letters and are assumed to be column vectors (unless transposed).
All matrices are denoted with uppercase Latin letters.

rotg :: Ptr a -> Ptr a -> Ptr a -> Ptr a -> IO () #

Generate a Givens rotation. (Only available for real floating-point types.)

rotmg :: Ptr a -> Ptr a -> Ptr a -> a -> Ptr a -> IO () #

Generate a modified Givens rotation. (Only available for real floating-point types.)

rot :: Int -> Ptr a -> Int -> Ptr a -> Int -> a -> a -> IO () #

Apply a Givens rotation. (Only available for real floating-point types.)

rotm :: Int -> Ptr a -> Int -> Ptr a -> Int -> Ptr a -> IO () #

Apply a modified Givens rotation. (Only available for real floating-point types.)

dsdot :: Int -> Ptr Float -> Int -> Ptr Float -> Int -> IO Double #

Calculate the dot product of two vectors with extended precision accumulation of the intermediate results and return a double-precision result. (Only available in the Double module.)

sdsdot :: Int -> Float -> Ptr Float -> Int -> Ptr Float -> Int -> IO Float #

Calculate the dot product of two vectors with extended precision accumulation of the intermediate results and add a scalar value to the result. (Only available for the Float type.)
