Description
BasicIterative
is a matrix equation
solver used in BasicSolverMode. It uses the ConjugateGradient method for symmetric
matrices and the ??? 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.
