#include "petsctao.h" PetscErrorCode TaoDefaultComputeHessian(Tao tao,Vec V,Mat H,Mat B,void *dummy)Collective on Tao
tao | - the Tao context | |
V | - compute Hessian at this point | |
dummy | - not used |
H | - Hessian matrix (not altered in this routine) | |
B | - newly computed Hessian matrix to use with preconditioner (generally the same as H) |
-tao_fd | - Activates TaoDefaultComputeHessian() | |
-tao_view_hessian | - view the hessian after each evaluation using PETSC_VIEWER_STDOUT_WORLD |
