For a 2D grid, use this module, which is adapted from the article "How to create a grid of values"

start ExpandGrid(_x1, _x2);

   x1 = colvec(_x1);  Nx = nrow(x1);

   x2 = rowvec(_x2);  Ny = ncol(x2);

   X = repeat(x1, 1, Ny);

   Y = repeat(x2, Nx);

   return ( colvec(X) || colvec(Y) );

finish;
