What exactly do ACML FFT routines compute ?

I'm a bit confused and couldn't get this information from the manual of ACML. Could someone tells me what exactly does the FFT routines of the ACML library computes?

I'm a C programmer, and I'm primarily concerned with FFT3D, so information on the order of the output element would be greatly appreciated as well. if my input matrix R_lmn,  (l,m,n) run from 0 to N, then is the order of the output matrix would be K_lmn, with (l,m,n) run from 0 to N as well ?

Thank you!
