Struct ExpmActionPlan 

pub struct ExpmActionPlan { /* private fields */ }

Prepared Al-Mohy–Higham exponential-action plan.

Construction computes the trace shift, exact stored one-norm, Taylor degree, and scaling count once. Repeated vector and batch applications then perform only matrix-vector products and vector updates.

Implementations

impl ExpmActionPlan

pub fn new( operator: &(impl LinearOperator + ?Sized), coefficient: Complex64, max_degree: usize, tolerance: f64, max_substeps: usize, ) -> Result<Self>

pub const fn coefficient(&self) -> Complex64

pub const fn degree(&self) -> usize

pub const fn scaling(&self) -> usize

pub fn apply( &self, operator: &(impl LinearOperator + ?Sized), initial: &[Complex64], ) -> Result<Vec<Complex64>>
