元胞自动机（Cellular Automaton），复数为Cellular Automata，简称CA，也有人译为细胞自动机、点格自动机、分子自动机或单元自动机)。是一时间和空间都离散的动力系统。散布在规则格网 (Lattice Grid)中的每一元胞(Cell)取有限的离散状态，遵循同样的作用规则，依据确定的局部规则作同步更新。大量元胞通过简单的相互作用而构成精态系统的演化。由冯诺依曼在20世纪50年代发明。
其特点是时间、空间、状态都离散，每个变量只取有限多个状态，且其状态改变的规则在时间和空间上都是局部的。
将所有元胞自动机的动力学行为归纳为四大类（Wolfram. S.，1986):
⑴平稳型:自任何初始状态开始，经过一定时间运行后，元胞空间趋于一个空间平稳的构形，这里空间平稳即指每一个元胞处于固定状态。不随时间变化而变化。
⑵周期型：经过一定时间运行后，元胞空间趋于一系列简单的固定结构（Stable Patterns）或周期结构（Perlodical Patterns)。由于这些结构可看作是一种 滤波器（Filter），故可应用到 图像处理的研究中。
⑶混沌型：自任何初始状态开始，经过一定时间运行后，元胞自动机表现出混沌的非周期行为，所生成的结构的统计特征不再变止，通常表现为分形 分维特征。
⑷复杂型：出现复杂的局部结构，或者说是局部的混沌，其中有些会不断地传播。
上述分类，又可以分别描述为（ 谭跃进，1996； 谢惠民，1994；李才伟、1997）；
⑴均匀状态，即点态 吸引子，或称不动点；
⑵简单的周期结构，即周期性吸引子，或称周期轨；
⑶混沌的非周期性模式，即混沌吸引子；
⑷这第四类行为可以与 生命系统等复杂系统中的 自组织现象相比拟，但在 连续系统中没有相对应的模式。但从研究元胞自动机的角度讲，最具研究价值的具有第四类行为的元胞自动机，因为这类元胞自动机被认为具有"突现计算"(Emergent Computation）功能，研究表明，可以用作广义计算机（Universal Computer）以 仿真任意复杂的计算过程。另外，此类元胞自动机在发展过程中还表现出很强的不可逆（lrreversibility）特征，而且，这种元胞自动机在若干有限循环后，有可能会 "死"掉，即所有元胞的状态变为零。
function varargout = ES(varargin)
% ES MATLAB code for ES.fig
% ES, by itself, creates a new ES or raises the existing
% singleton*.
%
% H = ES returns the handle to a new ES or the handle to
% the existing singleton*.
%
% ES('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in ES.M with the given input arguments.

% stop. All inputs are passed to ES_OpeningFcn via varargin.
