Struct Certified 

Source 
pub struct Certified {
    pub x: Vec<Rational>,
    pub residual_zero: bool,
    pub nonsingular: bool,
}
Expand description

A solve carrying its own certificate: the exact solution plus independently re-checked flags that A·x = b holds exactly and det A ≠ 0. This is what “prove, not just run” means for a solve.

Fields§

§x: Vec<Rational>§residual_zero: bool

A·x == b verified by re-multiplication over exact rationals (not solver trust).

§nonsingular: bool

det A ≠ 0 — the system has a unique solution.
