Struct basic_dsp::conv_types::RealFrequencyLinearTableLookup

pub struct RealFrequencyLinearTableLookup<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> RealFrequencyLinearTableLookup<T> where     T: RealNumber,

Important traits for &'a mut [u8]

impl<'a> Write for &'a mut [u8]impl<'a> Read for &'a [u8]

pub fn table(&self) -> &[T]

Allows to inspect the generated lookup table

pub fn delta(&self) -> T

Gets the delta value which determines the resolution

impl RealFrequencyLinearTableLookup<f32>

pub fn from_raw_parts(     table: &[f32],     delta: f32,     is_symmetric: bool ) -> RealFrequencyLinearTableLookup<f32>

Creates a lookup table by putting the pieces together.

pub fn from_conv_function(     other: &dyn RealFrequencyResponse<f32>,     delta: f32,     len: usize ) -> RealFrequencyLinearTableLookup<f32>

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

impl RealFrequencyLinearTableLookup<f64>

pub fn from_raw_parts(     table: &[f64],     delta: f64,     is_symmetric: bool ) -> RealFrequencyLinearTableLookup<f64>

Creates a lookup table by putting the pieces together.

pub fn from_conv_function(     other: &dyn RealFrequencyResponse<f64>,     delta: f64,     len: usize ) -> RealFrequencyLinearTableLookup<f64>

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

impl RealFrequencyLinearTableLookup<f32>

pub fn to_complex(&self) -> ComplexFrequencyLinearTableLookup<f32>

Convert the lookup table into complex number space

impl RealFrequencyLinearTableLookup<f64>

pub fn to_complex(&self) -> ComplexFrequencyLinearTableLookup<f64>

Convert the lookup table into complex number space

Trait Implementations
