Struct CholUpdateConfig 

pub struct CholUpdateConfig {
    pub check_positive_definite: bool,
    pub tolerance: f64,
}

Configuration for Cholesky update/downdate operations.

Controls numerical checks and tolerances used during the modification of a Cholesky factorization.

Example

use scirs2_sparse::cholesky_update::CholUpdateConfig;

let config = CholUpdateConfig {
    check_positive_definite: true,
    tolerance: 1e-12,
};

Fields

check_positive_definite: bool

Whether to verify positive definiteness of the result.

When true, the algorithm checks that all diagonal elements of the updated factor remain positive, returning an error if the result would be indefinite (particularly relevant for downdates).

tolerance: f64

Numerical tolerance for zero-checks and stability decisions.

Diagonal elements below this threshold are considered numerically zero, triggering a positive-definiteness failure when checking is enabled.
