Preconditioners

Overview

In many cases, applying a preconditioner to the coefficient matrix reduces the number of iterations necessary to solve the system. The Sparse Solvers library provides Jacobi and diagonal scaling preconditioners, and the functionality to create user-defined preconditioners.
