Struct ComplexTimeLinearTableLookup

Source 
pub struct ComplexTimeLinearTableLookup<T>
where
    T: RealNumber,
{ /* private fields */ }
Expand description

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

Implementations§

Source§

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

Source

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

Allows to inspect the generated lookup table

Source

pub fn delta(&self) -> T

Gets the delta value which determines the resolution

Source§

impl ComplexTimeLinearTableLookup<f32>

Source

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

Creates a lookup table by putting the pieces together.

Source

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