!* Print out a matrix.                                                       *
!*  Should really align with the F77 version under the SERIAL dir, which     *
!*  does a nice printout in MatrixMarket format; this would be a quick job.  *

!*  Handles both a shift in the row/col indices and a fuctional transform    *
!*  on the indices.                                                          *
