   Why not do what I do and have the best of both worlds? Allocate one long
   array of nx*ny doubles, then an array of nx double*s, each of which points
   to the appropriate section of the previous array. Operations that naturally
   run across the entire array can be coded like that, and operations that
   make use of the 2Dness of the array can be coded like that. You also have
   something you can pass to Fortran.

I posted C code for this in this very group about a week ago...

   Of course I wrap it up in a C++ class to
   hide the ugly details of creating and destroying the objects each time I
   use them.

C++ code for implementing template arrays in this way is available
from "maya.idiap.ch:pub/tmb/array.shar".
