- * Computes the split-radix FFT in place for the real-valued

- *
- * The function needs sine and cosine tables t_sin and t_cos,

- * sin(2*pi*i) and cos(2*pi*i) for i = 0, 1, ..., N_MAX_FFT-1. The
- * implementation assumes that any entry will not be needed
- * outside the tables. Therefore, N_MAX_FFT and n must be properly

- * 32, 64, 128, 256, and N_MAX_FFT = 1280.
