Function rgsl::fft::real_radix2::backward

pub fn backward(data: &mut [f64], stride: usize, n: usize) -> Value

This function computes the inverse or backwards in-place radix-2 FFT of length n and stride stride on the half-complex sequence data stored according the output scheme used by gsl_fft_real_radix2. The result is a real array stored in natural order.
