GRID_DISPLAY is a MATLAB program which can read an ASCII file defining a set of points on a 1D, 2D or 3D grid or sparse grid, and display a plot of those points, inside a plot frame of user-specified range [Rmin,Rmax].
grid_display ( 'file_name', rmin, rmax )where

GRID_DISPLAY is available in a MATLAB version.
BALL_AND_STICK_DISPLAY, a MATLAB program which demonstrates the creation of a 3D "ball and stick" image;
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.
GRIDLINES, a MATLAB library which gives the user more control over drawing gridlines on a graph than the builtin "grid on" command.
GRIDS_DISPLAY, a MATLAB program which reads two files of grids or sparse grids, displays the first with hollow blue dots, the second with red dots.
NESTED_SEQUENCE_DISPLAY, a MATLAB program which displays a set of nested sequences.
PLY_DISPLAY, a MATLAB program which displays an image of a 3D graphics file in PLY format;
QUADRATURE_RULES, a dataset directory which defines quadrature rules; a number of examples of sparse grid quadrature rules are included.
TENSOR_GRID_DISPLAY, a MATLAB program which can display the grid points of a tensor product rule used for interpolation or quadrature, in 1D, 2D or 3D.
XY, a data directory which contains some examples of 2D pointsets.
XY_DISPLAY, a MATLAB program which can read a file of coordinates of points, and display an image of the points in a MATLAB graphics window.
XY_DISPLAY_OPENGL, a C++ program which can read a file containing 2D point coordinates, and display an image of those points using Open GL.
