TaoSetJacobianInequalityRoutine#

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

Synopsis#

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

Logically collective

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
