NEPJacobianFn#

A prototype of a NEP Jacobian evaluation function that would be passed to NEPSetJacobian().

Synopsis#

PETSC_EXTERN_TYPEDEF typedef PetscErrorCode NEPJacobianFn(NEP nep,PetscScalar lambda,Mat J,void *ctx);

Calling Sequence#

  • nep - the nonlinear eigensolver context

  • lambda - the scalar argument where \(T'(\cdot)\) must be evaluated

  • J - matrix that will contain \(T'(\lambda)\)

  • ctx - [optional] user-defined context for private data for the Jacobian evaluation routine (may be NULL)
