Conway Game of Life Help

We would like our code to display the changes of every iteration on the image but when it is run now, we just get a black grid. Also, we would like to do a count on the number of "live" cells (1s), and have the program end when the number stabilizes.

Any ideas? Thank you!

% function [n] = Life_m(n)
n=45;
board= zeros(100,100); % pre-allocate board size
v = [1*ones(n,1) ; 0*ones(100-n,1)];
colormap(gray(2));

for ii = 1:100
   board(:,ii) = v(randperm(100));
end

for m = 1:100
%calculate neighbors for left edge w/o corners

    for jj = 2:99
        neighbors = board(ii+1,jj)+board(ii,jj+1)+board(ii,jj-1)...
        +board(ii+1,jj+1)+board(ii+1,jj-1);

Answer 1

[A Jenkins]

1) neighbors(ii,jj) not neighbors

2) I prefer spy(board) to image(board)

3) You can count nonzero elements with nnz(board)
