Function ls_solver::api::compute_precision

pub fn compute_precision(
    a: &CsrMatrix<f64>,
    solution: &DVector<f64>,
    method: Method,
    tol: f64,
    max_iter: i32,
    omega: f64
) -> Performance

Determines the accuracy of x (solution computed by the routine) against the correct one and returns an istance of Performance.

Where x is the solution of the system ax = b, with b := a*solution.

Arguments:

• a: matrix
• solution: the given solution of the system
• method: an istance of the enum Method
• tol: the tolerance required to stop the routine
• max_iter: the maximum number of iteration after wich the routine stops
• omega: the relaxation factor, used only if method is either Jacobi or Gauss-Seidel
