#include "slepcnep.h" PetscErrorCode NEPSetJacobian(NEP nep,Mat A,PetscErrorCode (*jac)(NEP,PetscScalar,Mat,void*),void *ctx)Logically Collective on nep
| 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) |
jac(NEP nep,PetscScalar lambda,Mat J,void *ctx)
| nep | - the NEP context | |
| lambda | - the scalar argument where T'(.) must be evaluated | |
| J | - matrix that will contain T'(lambda) | |
| ctx | - (optional) user-defined context, as set by NEPSetJacobian() |
