Efficient conversion between Primitive vectors and Accelerate Arrays.

type Vectors e = GArrayDataR Vector e

A family of types which represent a collection of Primitive Vectors. The structure of the collection depends on the element type e of the corresponding Accelerate array.

toVectors :: forall sh e. (HasCallStack, Shape sh, Elt e) => Array sh e -> Vectors (EltR e)

O(1) (typically). Convert an Accelerate array into a collection of primitive vectors.

If the array data was allocated by Accelerate, this can typically be done without copying.

since 0.1.0.0

fromVectors :: forall sh e. (HasCallStack, Shape sh, Elt e) => sh -> Vectors (EltR e) -> Array sh e

O(n) (typically). Convert a collection of primitive vectors into an Accelerate array.

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