GRIDS_DISPLAY, a MATLAB program 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.

GRIDS_DISPLAY is available in a MATLAB version.
CC_DISPLAY, a MATLAB program which displays points on various grids derived from the Clenshaw Curtis rule.
CIRCLE_GRID_DISPLAY, a MATLAB program which reads a matrix of integers, and draws a corresponding grid of circles filled with color.
GL_DISPLAY, a MATLAB program which displays points on various grids derived from the Gauss-Legendre rule.
GRID_DISPLAY, a MATLAB program 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 library which gives the user more control over drawing gridlines on a graph than the builtin "grid on" command.
PLY_DISPLAY, a MATLAB program which displays an image of a 3D graphics file in PLY format;
