Hello, I was hoping someone here could help. I am writing some code for a Cellular Automata Simulator. I would like to have a function that I can give the following information to: Grid[size_of_grid, matrix_of_cells_to_fill] This function will draw a n x m rectangular grid = size (for example size = {2,2} for a 2 x 2 grid). I then will pass an array of the cells to be filled. For example {{1,1},{2,2}}. It could also be {{1,1},{1,2},{2,1},{2,2}}, in which case the whole grid will have filled cells. The Grid function will then return a Rectangular Grid with the cells (1,1) and (2,2), which are the diagonal cells filled in as either black cells or, better yet, as filled in circles that are smaller in size than the square grid cell size. (Little circles enclosed within the grid cells). Can someone help me with this function (I don't think that such a thing would be difficult for an experienced Mathematica user, but one never knows). Also, I am using Mathematica V. 3.0. I got 4.0, but there are various install issues that I am working through. Thank you for any assistance.
