Dear folks,
     Here are some problems when I'm using the new PETSc and tried to 
run src/ksp/ksp/example/tutorial/ex45.c
1, when I compile it, it says that 'DMSetInitialGuess' can not be found. 
So, I commented it out; however, this command still appears in 
Therefore, I wonder if my PETSc has not been updated correctly.
2, in old version code, I implemented a post-processing code using:
   ierr = DMDAGetCoordinateDA(da, &cda);
   ierr = DMDAGetGhostedCoordinates(da, &gc);
   ierr = DMDAVecGetArray(cda, gc, &coors);
     in order to get the locations of 'coors' stored in 'DM da'. 
However, the current version seems does not have 'DMDAGetCoordinateDA' 
and 'DMDAGetGhostedCoordinates'. Then, what should I do to get the 
'coors'? Specifically, what should I do to get 'Vec gc'.
