**box_games**,
a MATLAB code which
contains utilities for creating and displaying simple board games,
such as for checkers, or life, or a cellular automaton.

**box_games** is available in
a MATLAB version and
an Octave version.

box_display, a MATLAB code which displays a box plot, over integer pairs of data, of a function defined by two formulas.

box_plot, a MATLAB code which displays a box plot of data that consists of pairs of integers;

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 the abscissas used in various kinds of Gauss Legendre quadrature rules.

gridlines, a MATLAB code which gives the user more control over drawing gridlines on a graph than the builtin "grid on" command.

lights_out, a MATLAB code which sets up the "Lights Out" game and allows a user to try to solve it.

prime_plot a MATLAB code which displays a box plot of the prime and composite numbers.

usa_box_plot, a MATLAB code which can create simplified maps of the USA in which each state appears as a box, and the placement of the boxes only roughly corresponds to the relative locations of states on an accurate map.
