grids_display, a MATLAB code which can read two ASCII files defining grids or sparse grids in 2D or 3D. The first grid is plotted "lightly", in hollow blue dots, while the second is plotted with solid red dots. The image is automatically saved to a PNG file.

cc_display, a MATLAB code which displays points on various grids derived from the Clenshaw Curtis rule.
circle_grid_display, a MATLAB code which reads a matrix of integers, and draws a corresponding grid of circles filled with color.
gl_display, a MATLAB code which displays points on various grids derived from the Gauss-Legendre rule.
grid_display, a MATLAB code which reads a file of points on a grid or sparse grid, displays the grid and saves the image in a PNG file;
gridlines, a MATLAB code which gives the user more control over drawing gridlines on a graph than the builtin "grid on" command.
quadrature_rules, a dataset directory which contains quadrature rules; a number of examples of sparse grid quadrature rules are included.
tensor_grid_display, a MATLAB code which can display the grid points of a tensor product rule used for interpolation or quadrature, in 1D, 2D or 3D.
