Struct ExponentialConvergence 

pub struct ExponentialConvergence {
    pub smoothness: u32,
    pub error: f64,
}

Spectral (exponential) convergence for smooth functions.

Fields

smoothness: u32

Smoothness class (number of continuous derivatives or ∞ = 99).

error: f64

Observed or estimated maximum error.

Implementations

impl ExponentialConvergence

pub fn new(smoothness: u32, error: f64) -> Self

Create a new ExponentialConvergence object.

pub fn spectral_accuracy(&self) -> bool

True if the method achieves spectral (super-algebraic) accuracy.

pub fn algebraic_vs_spectral(&self, n: usize) -> (f64, f64)

Compare algebraic vs spectral convergence rates for n modes.

Returns (algebraic_error, spectral_error) for illustration.
