PETSc version 3.15.5
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 |
