TaoLineSearchGetNumberFunctionEvaluations
Gets the number of function and gradient evaluation routines used by the line search in last application (not cumulative). 
Synopsis
#include "petsctaolinesearch.h" 
PetscErrorCode TaoLineSearchGetNumberFunctionEvaluations(TaoLineSearch ls, PetscInt *nfeval, PetscInt *ngeval, PetscInt *nfgeval)
Not Collective
Input Parameter
|  | ls | - the TaoLineSearch context | 
Output Parameters
|  | nfeval | - number of function evaluations | 
|  | ngeval | - number of gradient evaluations | 
|  | nfgeval | - number of function/gradient evaluations | 
Note
If the line search is using the Tao objective and gradient
routines directly (see TaoLineSearchUseTaoRoutines()), then TAO
is already counting the number of evaluations.
