transform :: (Shape sh, Slice sh, Real e) => Handle (sh :. Int) e a b -> Transform (sh :. Int) a b Source #
The implementation works on all arrays of rank less than or equal to 3. The result is un-normalised.
plan1D :: (Shape sh, Slice sh, Elt e, Real e) => PTX -> Mode (Batch1 sh) e a b -> Batch1 sh -> IO (Handle (Batch1 sh) e a b) Source #
plan2D :: (Shape sh, Slice sh, Elt e, Real e) => PTX -> Mode (Batch2 sh) e a b -> Batch2 sh -> IO (Handle (Batch2 sh) e a b) Source #
plan3D :: (Shape sh, Slice sh, Elt e, Real e) => PTX -> Mode (Batch3 sh) e a b -> Batch3 sh -> IO (Handle (Batch3 sh) e a b) Source #
class (RealFloat e, RealFloat e, FromIntegral Int e) => Real e Source #

In contrast to plain CUFFT functions the data is redundant.
That is, an array of shape sh is transformed to an array of shape sh.
This way, all dimensions of an array are handled the same way.
Chances are good,
that the internal post processing is fused with following array operations
and thus the redundant data will not be stored in a manifest array.
