#include "petscmat.h" #include "petscsnes.h" PetscErrorCode PETSCSNES_DLLEXPORT SNESDefaultComputeJacobianColor(SNES snes,Vec x1,Mat *J,Mat *B,MatStructure *flag,void *ctx)Collective on SNES
| snes | - nonlinear solver object | |
| x1 | - location at which to evaluate Jacobian | |
| ctx | - coloring context, where ctx must have type MatFDColoring, as created via MatFDColoringCreate() |
| J | - Jacobian matrix (not altered in this routine) | |
| B | - newly computed Jacobian matrix to use with preconditioner (generally the same as J) | |
| flag | - flag indicating whether the matrix sparsity structure has changed |
