#include "slepcds.h" PetscErrorCode DSNEPSetComputeMatrixFunction(DS ds,PetscErrorCode (*fun)(DS,PetscScalar,PetscBool,DSMatType,void*),void *ctx)Logically Collective on DS
| ds | - the direct solver context | |
| fun | - a pointer to the user function | |
| ctx | - a context pointer (the last parameter to the user function) |
fun(DS ds,PetscScalar lambda,PetscBool deriv,DSMatType mat,void *ctx)
| ds | - the direct solver object | |
| lambda | - point where T(lambda) or T'(lambda) must be evaluated | |
| deriv | - if true compute T'(lambda), otherwise compute T(lambda) | |
| mat | - the DS matrix where the result must be stored | |
| ctx | - optional context, as set by DSNEPSetComputeMatrixFunction() |
