Struct basic_dsp_vector::conv_types::ComplexTimeLinearTableLookup

pub struct ComplexTimeLinearTableLookup<T> where T: RealNumber { /* fields omitted */ }

Allows to create a lookup table with linear interpolation between table points. This usually speeds up a convolution and sacrifices accuracy.

Methods

impl<T> ComplexTimeLinearTableLookup<T> where T: RealNumber

fn table(&self) -> &[Complex<T>]

Allows to inspect the generated lookup table

fn delta(&self) -> T

Gets the delta value which determines the resolution

impl ComplexTimeLinearTableLookup<f32>

fn from_raw_parts(table: &[Complex32], delta: f32, is_symmetric: bool) -> Self

Creates a lookup table by putting the pieces together.

fn from_conv_function(other: &ComplexImpulseResponse<f32>,
                      delta: f32,
                      len: usize)
                      -> Self

Creates a lookup table from another convolution function. The delta argument can be used to balance performance vs. accuracy.

impl ComplexTimeLinearTableLookup<f64>

fn from_raw_parts(table: &[Complex64], delta: f64, is_symmetric: bool) -> Self

Creates a lookup table by putting the pieces together.

fn from_conv_function(other: &ComplexImpulseResponse<f64>,
                      delta: f64,
                      len: usize)
                      -> Self

Creates a lookup table from another convolution function. The delta argument can be used to balance performance vs. accuracy.
