Uses of Preconditioner in dev.nm.algebra.linear.matrix.doubles.matrixtype.sparse.solver.iterative.preconditioner
Classes in dev.nm.algebra.linear.matrix.doubles.matrixtype.sparse.solver.iterative.preconditioner that implement Preconditioner Modifier and Type Class Description classIdentityPreconditionerThis identity preconditioner is used when no preconditioning is applied.classJacobiPreconditionerThe Jacobi (or diagonal) preconditioner is one of the simplest forms of preconditioning, such that the preconditioner is the diagonal of the coefficient matrix, i.e., P = diag(A).classSSORPreconditionerSSOR preconditioner is derived from a symmetric coefficient matrix A which is decomposed as A = D + L + Lt The SSOR preconditioning matrix is defined as M = (D + L)D-1(D + L)t or, parameterized by ω M(ω) = (1/(2 - ω))(D / ω + L)(D / ω)-1(D / ω + L)tMethods in dev.nm.algebra.linear.matrix.doubles.matrixtype.sparse.solver.iterative.preconditioner that return Preconditioner Modifier and Type Method Description PreconditionerPreconditionerFactory. newInstance(Matrix A)Construct a new instance ofPreconditionerfor a coefficient matrix.
