Fields

n: usize

Number of samples N.

dim: usize

Number of columns d.

l: usize

Hankel parameter L.

x_min: f64

Sampling interval.

x_max: f64

Sampling interval.

s: Vec<f64>

Singular values of the Hankel matrix (empty for zero input).

m: usize

Number of nodes M.

sigma: f64

S[M], the first discarded singular value (0 for zero input).

gamma: Vec<Complex<f64>>

Nodes γ_j.

omega: Vec<Complex<f64>>

Weights ω_j, column-major M x d.

err_max: f64

Maximum error of the approximation on the samples.

err_ave: f64

Largest mean (over samples) error among the columns.

Implementations

impl Esprit

pub fn new( h: &[Complex<f64>], n: usize, dim: usize, p: &EspritParams, ) -> Result<Self>

ESPRIT of h (column-major n x dim).

Errors

Error::InvalidParameter for invalid parameters, and Error::DecompositionFailed if no controlled approximation exists.

pub fn get_value(&self, x: &[f64]) -> Vec<Complex<f64>>

The approximation at points x (column-major len(x) x d).

pub fn get_value_indiv(&self, x: f64, col: usize) -> Complex<f64>

The approximation of column col at x.

Trait Implementations
