Class xlifepp::PreconditionerTerm#

class PreconditionerTerm : public xlifepp::Preconditioner #

Define the preconditioner for linear systems.

This is a main class that users can derive to deal with preconditioning by operators. In most of the cases, users will use xlifepp::PreconditionerTerm when it is a preconditioning with TermMatrix/TermVector level (or MatrixEntry/VectorEntry)
