Struct IluOperator 

pub struct IluOperator { /* private fields */ }

ILU preconditioner wrapper implementing LinearOperator

This wraps the ILU preconditioner to work with the LinearOperator interface.

Implementations

impl IluOperator

pub fn new(preconditioner: IluPreconditioner, n: usize) -> Self

Create from an ILU preconditioner

pub fn from_tbem_matrix(matrix: &Array2<Complex64>) -> Self

Create from a dense matrix with default settings for TBEM

pub fn from_matrix( matrix: &Array2<Complex64>, method: IluMethod, degree: IluScanningDegree, ) -> Self

Create from a dense matrix with specified method and degree

pub fn fill_ratio(&self) -> f64

Get fill ratio (nnz(L+U) / n^2)
