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.


#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.
jac - Jacobian evaluation routine
ctx - [optional] user-defined context for private data for the Jacobian evaluation routine (may be NULL)

Calling sequence of jac

   jac (Tao tao,Vec x,Mat *J,Mat *Jpre,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
