#include "petscmat.h" PetscErrorCode MatMFFDSetBase(Mat J,Vec U,Vec F)Logically Collective on Mat
| J | - the MatMFFD matrix | |
| U | - the vector | |
| F | - (optional) vector that contains F(u) if it has been already computed |
Notes: This is rarely used directly
If F is provided then it is not recomputed. Otherwise the function is evaluated at the base point during the first MatMult() after each call to MatMFFDSetBase().
