Struct RrLUOptions 

pub struct RrLUOptions {
    pub max_rank: usize,
    pub rel_tol: f64,
    pub abs_tol: f64,
    pub left_orthogonal: bool,
}

Options for rank-revealing LU decomposition.

Examples

use tensor4all_tcicore::RrLUOptions;

// Default: rel_tol = 1e-14, no absolute tolerance, no rank limit
let opts = RrLUOptions::default();
assert_eq!(opts.rel_tol, 1e-14);
assert_eq!(opts.abs_tol, 0.0);
assert!(opts.left_orthogonal);

// Limit rank to 5
let opts = RrLUOptions { max_rank: 5, ..Default::default() };
assert_eq!(opts.max_rank, 5);

Fields

max_rank: usize

Maximum rank

rel_tol: f64

Relative tolerance

abs_tol: f64

Absolute tolerance

left_orthogonal: bool

Left orthogonal (L has 1s on diagonal) or right orthogonal (U has 1s)
