#include "petsctao.h" PetscErrorCode TaoSetHessianRoutine(Tao tao, Mat H, Mat Hpre, PetscErrorCode (*func)(Tao, Vec, Mat, Mat, void*), void *ctx)Logically collective on Tao
| tao | - the Tao context | |
| H | - Matrix used for the hessian | |
| Hpre | - Matrix that will be used operated on by preconditioner, can be same as H | |
| hess | - Hessian evaluation routine | |
| ctx | - [optional] user-defined context for private data for the Hessian evaluation routine (may be NULL) |
hess (Tao tao,Vec x,Mat H,Mat Hpre,void *ctx);
| tao | - the Tao context | |
| x | - input vector | |
| H | - Hessian matrix | |
| Hpre | - preconditioner matrix, usually the same as H | |
| ctx | - [optional] user-defined Hessian context |
