Methods

impl DiscreteHankel

pub fn new(size: usize) -> Option<DiscreteHankel>

This function allocates a Discrete Hankel transform object of size size.

pub fn new_with_init(size: usize, nu: f64, xmax: f64) -> Option<DiscreteHankel>

This function allocates a Discrete Hankel transform object of size size and initializes it for the given values of nu and xmax.

pub fn init(&mut self, nu: f64, xmax: f64) -> Value

This function initializes the transform self for the given values of nu and xmax.

pub fn apply(&self, f_in: &[f64]) -> Result<Vec<f64>, Value>

This function applies the transform t to the array f_in whose size is equal to the size of the transform. The result is stored in the array f_out which must be of the same length.

Applying this function to its output gives the original data multiplied by (1/j_(\nu,M))^2, up to numerical errors.

pub fn x_sample(&self, n: i32) -> f64

This function returns the value of the n-th sample point in the unit interval, (j_{\nu,n+1}/j_{\nu,M}) X. These are the points where the function f(t) is assumed to be sampled.

pub fn k_sample(&self, n: i32) -> f64

This function returns the value of the n-th sample point in “k-space”, j_{\nu,n+1}/X.
