中文说明：在matlab R2009b调试通过，基于互功率谱的时延估计，该函数用来计算任意函数的一阶偏导数(数值方法),基于matlab平台实现,matlab编写的元胞自动机，详细画出了时域和频域的相关图。
English Description：
In the MATLAB r2009b debugging through, based on the cross power spectrum time delay estimation, the function used to calculate any function of the first order partial derivative (numerical method), is implemented based on the MATLAB platform, matlab cellular automata, with painting the time domain and frequency domain correlation diagram.
