# NEPSetJacobian

Sets the function to compute Jacobian T'(lambda) as well as the location to store the matrix.

### Synopsis

    #include "slepcnep.h"
    PetscErrorCode NEPSetJacobian(NEP nep,Mat A,PetscErrorCode (*jac)(NEP,PetscScalar,Mat,void*),void *ctx)

Logically Collective on NEP and Mat

### Input Parameters

| nep | - the NEP context
| A | - Jacobian matrix
| jac | - Jacobian evaluation routine (if NULL then NEP retains any previously set value)
| ctx | - [optional] user-defined context for private data for the Jacobian evaluation routine (may be NULL) (if NULL then NEP retains any previously set value)
