    PetscErrorCode NEPComputeJacobian(NEP nep,PetscScalar lambda,Mat A)

Collective on NEP and Mat

### Input Parameters

| nep | - the NEP context
| lambda | - the scalar argument

### Output Parameters

| A | - Jacobian matrix

### Notes

Most users should not need to explicitly call this routine, as it is used internally within the nonlinear eigensolvers.
