Struct IterSolver 

pub struct IterSolver<T: Scalar> { /* private fields */ }

RAII handle for the AOCL-Sparse iterative-solver suite.

Configure the solver type and tolerances with IterSolver::set_option (e.g. set_option("iterative method", "cg") or "gmres"), then call IterSolver::solve with the system matrix and right-hand side.

Implementations

impl<T: Scalar> IterSolver<T>

pub fn new() -> Result<Self>

Initialise a new iterative-solver handle for this scalar type.

pub fn set_option(&mut self, name: &str, value: &str) -> Result<()>

Set a string-keyed solver option. See AOCL-Sparse’s aoclsparse_itsol_option_set for the full option list. Common keys: "iterative method" ("cg"/"gmres"/"pcg"), "cg iteration limit", "cg rel tolerance", "gmres preconditioner".

pub fn solve( &mut self, mat: &SparseMatrix<T>, descr: &MatDescr, b: &[T], x: &mut [T], ) -> Result<Box<[T; 100]>>

where T: Default,

Solve A · x = b. On entry x should hold an initial guess (zero is fine if you have nothing better); on success it contains the approximate solution. Returns the solver’s rinfo[100] array of statistics (iteration counts, residual norms, etc.).
