TaoSetJacobianEqualityRoutine

Sets the function to compute the Jacobian (and its inverse) of the constraint function with respect to the equality variables. Used only for pde-constrained optimization.

Synopsis

#include "petsctao.h" 
PetscErrorCode TaoSetJacobianEqualityRoutine(Tao tao, Mat J, Mat Jpre, PetscErrorCode (*func)(Tao, Vec, 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.
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,void *ctx);

tao - the Tao context
x - input vector
J - Jacobian matrix
Jpre - preconditioner matrix, usually the same as J
ctx - [optional] user-defined Jacobian context
