c  Include this file to get timing statistics for the different parts
c  of the Arnoldi update iteration.  An easy way to initialize all the
c  timing information to zero at the beginning is by:
c
c     call sstats  <-- symmetric code
c     call sstatn  <-- nonsymmetric code
c     call cstatn  <-- complex code

c
c  nopx   = total number of user OP*x operation
c  nbx    = total number of user B*x operation (same as copy when B = I)
c  nrorth = total number of reorthogonalization steps taken
c  nitref = total number of it. refinement steps in reorthogonalization
c  nrstrt = total number of restart steps
