/*
PFFFT : a Pretty Fast FFT.
This is basically an adaptation of the single precision fftpack
(v4) as found on netlib taking advantage of SIMD instruction found
on cpus such as intel x86 (SSE1), powerpc (Altivec), and arm (NEON).
For architectures where no SIMD instruction is available, the code
falls back to a scalar version.
Restrictions:
- 1D transforms only, with 32-bit single precision.
- supports only transforms for inputs of length N of the form
N=(2^a)*(3^b)*(5^c), a >= 5, b >=0, c >= 0 (32, 48, 64, 96, 128,
144, 160, etc are all acceptable lengths). Performance is best for
128<=N<=8192.
- all (float*) pointers in the functions below are expected to
have an "simd-compatible" alignment, that is 16 bytes on x86 and
powerpc CPUs.
You can allocate such buffers with the functions
pffft_aligned_malloc / pffft_aligned_free (or with stuff like
posix_memalign..)

the forward fft, and before the backward fft.
Transforms are not scaled: PFFFT_BACKWARD(PFFFT_FORWARD(x)) = N*x.
Typically you will want to scale the backward transform by 1/N.
