MatStructure *flag,void *ctx)
Collective on
SNES
| x1 | - compute Hessian at this point |
| ctx | - application's gradient context, as set with SNESSetGradient() |
| J | - Hessian matrix (not altered in this routine) |
| B | - newly computed Hessian matrix to use with preconditioner (generally the same as J) |
| flag | - flag indicating whether the matrix sparsity structure has changed |
-snes_fd - Activates SNESDefaultComputeHessian()
