DSNEPSetFN
Sets a number of functions that define the nonlinear eigenproblem.
Synopsis
#include "slepcds.h"
PetscErrorCode DSNEPSetFN(DS ds,PetscInt n,FN fn[])
Collective
Input Parameters
| ds | - the direct solver context
|
| n | - number of functions
|
| fn | - array of functions
|
Notes
The nonlinear eigenproblem is defined in terms of the split nonlinear
operator T(lambda) = sum_i A_i*f_i(lambda).
This function must be called before DSAllocate(). Then DSAllocate()
will allocate an extra matrix A_i per each function, that can be
filled in the usual way.
