toUnboxed :: forall sh e. (Shape sh, Unbox e) => Array sh e -> Vector e Source #

O(1) (typically). Convert an Accelerate array into an Unboxed vector.

If the array data was allocated by Accelerate, this can typically be done without copying. The resulting vector will be pinned.

fromUnboxed :: Unbox e => Vector e -> Array DIM1 e Source #

O(n) (typically). Convert an Unboxed vector into an Accelerate array.

If the underlying vectors are pinned then this can be done without copying.
