Struct GmresOptions 

pub struct GmresOptions {
    pub max_iter: usize,
    pub rtol: f64,
    pub max_restarts: usize,
    pub verbose: bool,
    pub check_true_residual: bool,
}

Options for GMRES solver.

Fields

max_iter: usize

Maximum number of iterations (restart cycle length). Default: 100

rtol: f64

Convergence tolerance for relative residual norm. The solver stops when ||r|| / ||b|| < rtol. Default: 1e-10

max_restarts: usize

Maximum number of restarts. Total iterations = max_iter * max_restarts. Default: 10

verbose: bool

Whether to print convergence information. Default: false

check_true_residual: bool

When true, verify convergence by computing the true residual ||b - A*x|| / ||b|| before declaring convergence. This prevents false convergence caused by truncation corrupting the Krylov basis orthogonality (see Issue #207). Costs one additional apply_a call when convergence is detected. Default: false
