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 - eigensolver context obtained from NEPCreate()
lambda - the scalar argument where T’(.) 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)
