Class GMRES

  • All Implemented Interfaces:
    IterativeSolver

    public class GMRES
    extends AbstractIterativeSolver
    GMRES solver. GMRES solves the unsymmetric linear system Ax = b using the Generalized Minimum Residual method. The GMRES iteration is restarted after a given number of iterations. By default it is restarted after 30 iterations.

      • GMRES

        public GMRES​(Vector template)
        Constructor for GMRES. Uses the given vector as template for creating scratch vectors. Typically, the solution or the right hand side vector can be passed, and the template is not modified. The iteration is restarted every 30 iterations
        Parameters:
        template - Vector to use as template for the work vectors needed in the solution process

        public GMRES​(Vector template,
                     int restart)
        Constructor for GMRES. Uses the given vector as template for creating scratch vectors. Typically, the solution or the right hand side vector can be passed, and the template is not modified
        Parameters:
        template - Vector to use as template for the work vectors needed in the solution process
        restart - GMRES iteration is restarted after this number of iterations
