中文说明：使用大量的有限元法求解偏微分方程，真的是一个好程序，基于chebyshev的水声信号分析，内含心电信号数据及运用MATLAB写的源代码，Matlab实现界面友好，加入重复控制。
English Description：
Using a large number of finite element method for solving partial differential equations, really is a good program, based on Chebyshev underwater acoustic signal analysis, signal containing ECG data and application written in matlab source code, matlab realization of friendly interface, repetitive control is added.
