Struct RealPlan2D 

pub struct RealPlan2D<T: Float> { /* private fields */ }

A plan for 2D real-to-complex and complex-to-real transforms.

For R2C: Takes n0×n1 real values and produces n0×(n1/2+1) complex values. For C2R: Takes n0×(n1/2+1) complex values and produces n0×n1 real values.

Implementations

impl<T: Float> RealPlan2D<T>

pub fn r2c(n0: usize, n1: usize, _flags: Flags) -> Option<Self>

Create a 2D R2C plan.

pub fn c2r(n0: usize, n1: usize, _flags: Flags) -> Option<Self>

Create a 2D C2R plan.

pub fn execute_r2c(&self, input: &[T], output: &mut [Complex<T>])

Execute the 2D real plan.

For R2C: input is n0×n1 real, output is n0×(n1/2+1) complex. For C2R: input is n0×(n1/2+1) complex, output is n0×n1 real.

pub fn execute_c2r(&self, input: &[Complex<T>], output: &mut [T])

Execute C2R transform.
