Iterative (BasicIterative) — Solve matrix equations approximately and iteratively, without using exta memory.
- Largest acceptable relative error in the matrix solution. Type: A real number.
- Maximum number of iterations to perform. Type: Integer.
BasicIterative is a matrix equation
solver used in BasicSolverMode. It uses the ConjugateGradient method for symmetric
matrices and the GeneralizedMinResidual method (with
krylov_dimension=30) for asymmetric matrices,
both of which are iterative methods appropriate for large sparse
matrices. In both cases it preconditions the matrix with the ILUPreconditioner.
