%% R8MAT_BORDER_ADD adds a "border" to an R8MAT.
%
%  Discussion:
%
%    An R8MAT is an array of R8's.
%
%    We suppose the input data gives values of a quantity on nodes
%    in the interior of a 2D grid, and we wish to create a new table
%    with additional positions for the nodes that would be on the
%    border of the 2D grid.

%
%    The illustration suggests the situation in which a 3 by 4 array
%    is input, and a 5 by 6 array is to be output.
%
%    The old data is shifted to its correct positions in the new array.
