Struct DeterminantWithErrorBound 

#[non_exhaustive]
pub struct DeterminantWithErrorBound { /* private fields */ }

A closed-form determinant and its certified absolute error bound.

Values of this type are produced by Matrix::det_direct_with_errbound. The paired result guarantees that the determinant was evaluated once and that its matching bound was computed for the same matrix in one call. The guarantee is unavailable when gradual underflow could invalidate the relative-error analysis or when the matrix dimension exceeds the closed-form D ≤ 4 scope.

Implementations

impl DeterminantWithErrorBound

pub const fn determinant(self) -> f64

Return the closed-form determinant approximation.

pub const fn absolute_error_bound(self) -> f64

Return the certified absolute error bound.

The exact determinant lies in [determinant - bound, determinant + bound].
