TaoSetHessian#
Sets the function to compute the Hessian as well as the location to store the matrix.
Synopsis#
#include "petsctao.h"
PetscErrorCode TaoSetHessian(Tao tao, Mat H, Mat Hpre, PetscErrorCode (*func)(Tao tao, Vec x, Mat H, Mat Hpre, void *ctx), void *ctx)
Logically Collective
Input Parameters#
tao - the
TaocontextH - Matrix used for the hessian
Hpre - Matrix that will be used to construct the preconditioner, can be same as
Hfunc - Hessian evaluation routine
ctx - [optional] user-defined context for private data for the Hessian evaluation routine (may be
NULL)
Calling sequence of func#
tao - the
Taocontextx - input vector
H - Hessian matrix
Hpre - matrix used to construct the preconditioner, usually the same as
Hctx - [optional] user-defined Hessian context
