Description

In rocFFT, is there a way to implement 1D batched FFT along a 3D array? I couldn't find a testset for Batch 1D (in 3D), and applying FFT on second dimension of a 3D array gives this error: ArgumentError: batching dims must be sequential
Is there a way to overcome this? Even an expensive solution would be acceptable, as I am looking for any possible workaround.
