#include "petsctao.h" PetscErrorCode TaoSetJacobianStateRoutine(Tao tao, Mat J, Mat Jpre, Mat Jinv, PetscErrorCode (*func)(Tao, Vec, Mat, Mat, Mat, void*), void *ctx)Logically collective on Tao
tao | - the Tao context | |
J | - Matrix used for the jacobian | |
Jpre | - Matrix that will be used operated on by PETSc preconditioner, can be same as J. Only used if Jinv is NULL | |
Jinv | - [optional] Matrix used to apply the inverse of the state jacobian. Use NULL to default to PETSc KSP solvers to apply the inverse. | |
func | - Jacobian evaluation routine | |
ctx | - [optional] user-defined context for private data for the Jacobian evaluation routine (may be NULL) |
func(Tao tao,Vec x,Mat J,Mat Jpre,Mat Jinv,void *ctx);
tao | - the Tao context | |
x | - input vector | |
J | - Jacobian matrix | |
Jpre | - preconditioner matrix, usually the same as J | |
Jinv | - inverse of J | |
ctx | - [optional] user-defined Jacobian context |
