Struct RealFftPlanner 

pub struct RealFftPlanner<T: Float> { /* private fields */ }

Real FFT planner for creating and managing FFT plans

This planner creates reusable FFT plans optimized for real-valued input/output. Plans are thread-safe and can be shared across threads using Arc.

Type Parameters

• T - Float type (f32 or f64)

Examples

use scirs2_fft::real_planner::RealFftPlanner;

let mut planner = RealFftPlanner::<f64>::new();
let forward = planner.plan_fft_forward(1024);
let inverse = planner.plan_fft_inverse(1024);

Implementations

impl RealFftPlanner<f64>

pub fn new() -> Self

Create a new planner for f64 precision

pub fn plan_fft_forward(&mut self, length: usize) -> Arc<dyn RealToComplex<f64>>

Create a forward FFT plan for real-to-complex transformation

Arguments

• length - Length of the input real-valued array

Returns

Arc-wrapped trait object implementing RealToComplex

pub fn plan_fft_inverse(&mut self, length: usize) -> Arc<dyn ComplexToReal<f64>>

Create an inverse FFT plan for complex-to-real transformation

Arguments
