Documentation

arrayFromVector :: Storable t => Vector t -> Array Int t

creates an immutable Array from an hmatrix Vector (to do: unboxed)

vectorFromArray :: Storable t => Array Int t -> Vector t

mArrayFromVector :: (MArray b t (ST s), Storable t) => Vector t -> ST s (b Int t)

creates a mutable array from an hmatrix Vector (to do: unboxed)

vectorFromMArray :: (Storable t, MArray a t (ST s)) => a Int t -> ST s (Vector t)

creates a mutable Array from an hmatrix Vector for manipulation with runSTUArray (to do: unboxed)

vectorToStorableArray :: Storable t => Vector t -> IO (StorableArray Int t)

Creates a StorableArray indexed from 0 to dim -1. (Memory is efficiently copied, so you can then freely modify the obtained array)

storableArrayToVector :: Storable t => StorableArray Int t -> IO (Vector t)

Creates a Vector from a StorableArray. (Memory is efficiently copied, so posterior changes in the array will not affect the result)

arrayFromMatrix :: Matrix Double -> UArray (Int, Int) Double

matrixFromArray :: UArray (Int, Int) Double -> Matrix Double

mArrayFromMatrix :: MArray b Double m => Matrix Double -> m (b (Int, Int) Double)

matrixFromMArray :: MArray a Double (ST s) => a (Int, Int) Double -> ST s (Matrix Double)
