有没有元胞自动机的matlab 代码

Answer 1

代码来自《元胞自动机与MATLAB》,是元胞自动机中“生命游戏”模型的代码
核心代码：

x = 2:n-1;
y = 2:n-1;
sum(x,y) = cells(x,y-1) + cells(x,y+1) + ...
cells(x-1, y) + cells(x+1,y) + ...
cells(x-1,y-1) + cells(x-1,y+1) + ...
cells(x+1,y-1) + cells(x+1,y+1);
cells = (sum==3) | (sum==2 & cells); %%%%此处出错
运行部分：

while (stop==0)
if (run==1)
%nearest neighbor sum
sum(x,y) = cells(x,y-1) + cells(x,y+1) + ... %%%此处出错
cells(x-1, y) + cells(x+1,y) + ...
cells(x-1,y-1) + cells(x-1,y+1) + ...
cells(3:n,y-1) + cells(x+1,y+1);
% The CA rule
cells = (sum==3) | (sum==2 & cells);
%draw the new image
set(imh, 'cdata', cat(3,cells,z,z) )
%update the step number diaplay
stepnumber = 1 + str2num(get(number,'string'));
set(number,'string',num2str(stepnumber))
end
if (freeze==1)
run = 0;
freeze = 0;
end
drawnow %need this in the loop for controls to work
end
