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 on Tao Many br

Input Parameters

tao - the Tao context Many br
J - Matrix used for the jacobian Many br
jac - Jacobian evaluation routine Many br
ctx - [optional] user-defined context for private data for the Many brJacobian evaluation routine (may be NULL) Many br

Calling sequence of jac

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

tao - the Tao context Many br
x - input vector Many br
J - Jacobian matrix Many br
ctx - [optional] user-defined Jacobian context Many br

Notes

The function jac() takes Mat * as the matrix arguments rather than Mat. Many brThis allows the Jacobian evaluation routine to replace A and/or B with a Many brcompletely new new matrix structure (not just different matrix elements) Many brwhen appropriate, for instance, if the nonzero structure is changing Many brthroughout the global iterations.
