int SNESCreate(MPI_Comm comm,SNESProblemType type,SNES *outsnes)Collective on MPI_Comm
comm | - MPI communicator |
type | - type of method, either SNES_NONLINEAR_EQUATIONS (for systems of nonlinear equations) or SNES_UNCONSTRAINED_MINIMIZATION (for unconstrained minimization) |
-snes_mf | - Activates default matrix-free Jacobian-vector products, and no preconditioning matrix |
-snes_mf_operator | - Activates default matrix-free Jacobian-vector products, and a user-provided preconditioning matrix as set by SNESSetJacobian() |
-snes_fd | - Uses (slow!) finite differences to compute Jacobian |
