where's that ? (I only see it in registered developer area, they launching in the forums again ? ::) )
Devaster:
yes in the forum only ...

so it seems that we must rearrange data before fft to real parts and imaginary parts in rhe same array and after this doing it back ....

Well AFAICT without bothering to look much further, they've simply added stride parameters, which would just require examining the data arrangement & setting the strides for the appropriate format you want. No doubt that makes some more advanced multidimensional FFTs easier to implement. For our purposes it'll probably just be a minor annoyance, to be overcome with macro definitions or wrapper functions.
