CIRCLE_GRID_DISPLAY
Display a Grid of Circles


CIRCLE_GRID_DISPLAY is a MATLAB program which reads a matrix of integers, and draws a corresponding grid of circles filled with color.

The program will display a grid of circles filled with colors according to the values in the matrix:

This program was designed in particular to make it possible to illustrate individual steps in the evolution of John Conway's Game of Life.
