TaoSetHessianRoutine
Sets the function to compute the Hessian as well as the location to store the matrix.
Synopsis
#include "petsctao.h"
PetscErrorCode TaoSetHessianRoutine(Tao tao, Mat H, Mat Hpre, PetscErrorCode (*func)(Tao, Vec, Mat, Mat, void*), void *ctx)
Logically collective on Tao
Input Parameters
| 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
|
| func | - Hessian evaluation routine
|
| ctx | - [optional] user-defined context for private data for the
Hessian evaluation routine (may be NULL)
|
Calling sequence of func
func(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
