If the array to be sorted is less than 64 entries long <A HREF="../Sys/PetscSortRealWithArrayInt.html#PetscSortRealWithArrayInt">PetscSortRealWithArrayInt</A>() is automatically used.
<P>
This function serves as an alternative to PetscSortRealWithArray(). While this function works for any array of PetscReals it is
significantly faster if the array is not totally random. There are exceptions to this and so it is __highly__
recomended that the user benchmark their code to see which routine is fastest.
