NEPFunctionFn#
A prototype of a NEP function evaluation function that would be passed to NEPSetFunction()
Synopsis#
PETSC_EXTERN_TYPEDEF typedef PetscErrorCode NEPFunctionFn(NEP nep,PetscScalar lambda,Mat T,Mat P,void *ctx);
Calling Sequence#
nep - eigensolver context obtained from NEPCreate()
lambda - the scalar argument where T(.) must be evaluated
T - matrix that will contain T(lambda)
P - [optional] different matrix to build the preconditioner
ctx - [optional] user-defined context for private data for the function evaluation routine (may be NULL)
