Struct ndrustfft::FftHandler [−][src]
pub struct FftHandler<T> { /* fields omitted */ }
Expand description
n-dimensional real-to-complex Fourier Transform.
Transforms a real ndarray of size n to a complex array of size n/2+1 and vice versa. The transformation is performed along a single axis, all other array dimensions are unaffected. Performs best on sizes which are mutiple of 2 or 3.
The accompanying functions for the forward transform are ndfft_r2c
(serial) and
ndfft_r2c_par
(parallel).
The accompanying functions for the inverse transform are ndifft_r2c
(serial) and
ndifft_r2c_par
(parallel).
Example
2-Dimensional real-to-complex fft along first axis
use ndarray::{Array2, Dim, Ix}; use ndrustfft::{ndfft_r2c, Complex, FftHandler}; let (nx, ny) = (6, 4); let mut data = Array2::<f64>::zeros((nx, ny)); let mut vhat = Array2::<Complex<f64>>::zeros((nx / 2 + 1, ny)); for (i, v) in data.iter_mut().enumerate() { *v = i as f64; } let mut fft_handler: FftHandler<f64> = FftHandler::new(nx); ndfft_r2c(&mut data, &mut vhat, &mut fft_handler, 0);
