TaoSetJacobianStateRoutine
Sets the function to compute the Jacobian (and its inverse) of the constraint function with respect to the state variables. Used only for pde-constrained optimization.
Synopsis
#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
Input Parameters
| 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)
|
Calling sequence of func
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
