The column on the right, "Pages", contain links to detailed information on rocFFT

rocFFT library includes the following Fourier transformation features

• 1D, 2D & 3D
• power of 2, 3, 5 and mix of them, from size 1 to 2^27. That is, the input sizes that can be written in the form 2^a × 3^b × 5^c. The smaller the prime factor, the better the performance, i.e., powers of two are fastest.
• Single and double precision
• Complex transforms
• Real transforms (internally uses complex)
• In-place and out-of-place transforms
• Interleaved layout, planar layout is not supported currently
• Unit (=1) stride (packed) for 2D and/or 3D. Unit and Non-unit stride (non-packed data) for 1D
