tensor_grid_display, an Octave code which displays the points of a 1D/2D/3D tensor product grid formed by the same rule in each dimension, but allowing the order of points in each dimension to vary.
For instance, it is legal to request a 3D grid using the Gauss-Legendre rule in each dimension, but with 3 points in X, 9 points in Y, and 5 points in Z.

cc_display, an Octave code which displays points on various grids derived from the Clenshaw Curtis rule.
circle_grid_display, an Octave code which reads a matrix of integers, and draws a corresponding grid of circles filled with color.
gl_display, an Octave code which displays points on various grids derived from the Gauss-Legendre rule.
grid_display, an Octave code which reads a file of points on a grid or sparse grid, displays the grid and saves the image in a PNG file;
grids_display, an Octave code which reads two files of grids or sparse grids, displays the first with hollow blue dots, the second with red dots.
nested_sequence_display, an Octave code which displays a set of nested sequences.
