Struct KrylovSettings 

pub struct KrylovSettings {
    pub tolerance: f64,
    pub max_iter: usize,
    pub restart: usize,
}

Iteration controls shared by bicgstab and gmres.

All fields are plain scalars with no units.

Fields

tolerance: f64

Relative convergence tolerance on ||b − A x||₂ / ||b||₂. Must be > 0; typical range 1e-12 .. 1e-4. Default 1e-8.

max_iter: usize

Maximum total number of iterations (matrix–vector products) before the solver returns unconverged. Default 1000.

restart: usize

GMRES restart length m — the Krylov subspace dimension per outer cycle, trading memory (O(m·n)) against convergence robustness. Ignored by BiCGStab. 0 means “no restart” (m = max_iter). Default 30.
