| Summary | 0000061: IMPLEMENTED: real FFT for general N (composite/prime) | ||||||
| Description |
Transforms implemented: * forward, real * backward, real N's supported - arbitrary: * even-sized tasks are solved using efficient reduction to complex FFT with factor of two savings * odd-sized tasks are solved using straightforward reduction to complex FFT (factor of two inefficient) Complexity: N*log(N) for composite/prime N's |
