Expand description

FFT planning and execution context

Fields§

§size: usize

Size of the transform

§algorithm: FFTAlgorithm

Algorithm to use

§twiddle_factors: Vec<Complex<F>>

Precomputed twiddle factors

§bit_reversal: Vec<usize>

Bit-reversal permutation indices

§real_input: bool

Whether this is for real input (RFFT)

Implementations§

Source §

impl<F> FFTPlan<F>
where F: Float + FloatConst,

Source

pub fn new( size: usize, algorithm: FFTAlgorithm, realinput: bool, ) -> LinalgResult<Self>

Create a new FFT plan for the given size

§Arguments

size - Transform size
algorithm - FFT algorithm to use
real_input - Whether input is real-valued

§Returns

FFT plan ready for execution

§Examples

use scirs2_linalg::fft::{FFTPlan, FFTAlgorithm};

let plan = FFTPlan::<f64>::new(1024, FFTAlgorithm::CooleyTukey, false).unwrap();
