Initialization and configuration

HYPRE.Init — Function
Init(; finalize_atexit=true)

Wrapper around HYPRE_Init. If finalize_atexit is true a Julia exit hook is added, which calls HYPRE_Finalize. This method will also call MPI.Init unless MPI is already initialized.

Note: This function must be called before using HYPRE functions.

Solvers and preconditioners

HYPRE.solve! — Function
solve!(solver::HYPRESolver, x::HYPREVector, A::HYPREMatrix, b::HYPREVector)

Solve the linear system A x = b using solver with x as the initial guess. The approximate solution is stored in x.

See also solve.

HYPRE.solve — Function
solve(solver::HYPRESolver, A::HYPREMatrix, b::HYPREVector) -> HYPREVector

Solve the linear system A x = b using solver and return the approximate solution.

This method allocates an initial guess/output vector x, initialized to 0.

See also solve!.
