BuildTable

{

This example shows the use of FlexPDE as a generator of data tables

in proper format to be read in by other FlexPDE problems.

We define a domain which is the domain of the table coordinates, and

compute and export the table.

No variables or equations are declared.

This example exports both a 1D and a 2D table of a Gaussian.
