Struct ConjugateGradientSolution 

pub struct ConjugateGradientSolution {
    pub x: Vec<f64>,
    pub relative_residual: f64,
    pub iterations: usize,
    pub status: Status,
}

The result of conjugate_gradient.

Fields

x: Vec<f64>

The final iterate.

relative_residual: f64

||b - A x||_2 / ||b||_2, recomputed from the matrix at the final iterate (zero when b is zero). A computed value, not an estimate.

iterations: usize

Iterations taken.

status: Status

Status::Converged when the relative residual met the tolerance, Status::BudgetExhausted when the iteration budget ran out first.

Implementations

impl ConjugateGradientSolution

pub fn converged(self) -> NumericResult<Self>

The solution when its tolerance was met.

Errors

NumericError::NotConverged with the relative residual reached.
