Most users should not need to know the details of the binary storage
format, since <A HREF="../DM/DMLoad.html#DMLoad">DMLoad</A>() and <A HREF="../DM/DMView.html#DMView">DMView</A>() completely hide these details.
But for anyone who's interested, the standard binary matrix storage
format is
<PRE>
has not yet been determined
</PRE>
<P>
In addition, PETSc automatically does the byte swapping for
machines that store the bytes reversed, e.g. DEC alpha, freebsd,
linux, Windows and the paragon; thus if you write your own binary
read/write routines you have to swap the bytes; see <A HREF="../Sys/PetscBinaryRead.html#PetscBinaryRead">PetscBinaryRead</A>()
and <A HREF="../Sys/PetscBinaryWrite.html#PetscBinaryWrite">PetscBinaryWrite</A>() to see how this may be done.
