TableDef

{  TABLEDEF.PDE  }

{

   This problem illustrates the use of the TABLEDEF function to define several parameters

       from an imported table named TABLEDEF.TBL

   Note that the TABLEDEF function has the same syntax as the TRANSFER function.

   The difference is that TABLEDEF uses a rectangular grid of data values, while TRANSFER uses

          an unstructured triangular finite element mesh.
