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 tao, Vec x, Mat J, Mat Jpre, void *ctx), void *ctx)

Logically Collective

Input Parameters

• tao - the Tao context

• J - Matrix used for the Jacobian

• Jpre - Matrix that will be used to construct the 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

• tao - the Tao context

• x - input vector

• J - Jacobian matrix

• Jpre - matrix used to construct the preconditioner, usually the same as J

• ctx - [optional] user-defined Jacobian context
