TaoSetJacobianDesignRoutine#

Sets the function to compute the Jacobian of the constraint function with respect to the design variables. Used only for PDE-constrained optimization.

Synopsis#

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

Logically Collective

Input Parameters#

  • tao - the Tao context

  • J - Matrix used for the Jacobian

  • func - Jacobian evaluation routine

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

Calling sequence of func#

PetscErrorCode func(Tao tao, Vec x, Mat J, void *ctx);

  • tao - the Tao context

  • x - input vector

  • J - Jacobian matrix

  • ctx - [optional] user-defined Jacobian context
