Struct DiagonalPreconditioner 

pub struct DiagonalPreconditioner { /* private fields */ }

Diagonal preconditioner from a linear operator

Extracts the diagonal and uses its inverse as a preconditioner.

Implementations

impl DiagonalPreconditioner

pub fn from_csr(matrix: &CsrMatrix) -> Self

Create from a CSR matrix

pub fn from_diagonal(diag: Array1<Complex64>) -> Self

Create from a diagonal vector

pub fn apply(&self, x: &Array1<Complex64>) -> Array1<Complex64>

Apply the preconditioner: y = M^{-1} * x
