该软件可以解析声音信号中的dtmf编码，值得下载一试。(The software can resolve the dtmf encoding sound signals)

说明：  《Matlab6.x符号计算与应用》机械工业出版社2003年版，刘宏友 彭锋 等编著。本书基于matlab6.0环境下的大量实例，介绍了matlab符号计算功能的适用方法。(Matlab6.x symbolic computation and application，China Machine Press, 2003 edition. LIU Hongyou-Peng Feng, eds. This book based on a large number of instances in matlab6.0 environment, introduced the application of matlab symbolic computing methods.)

可以完成地震记录的合成，实现地震记录的正演模拟(Synthetic seismogram can be done to achieve forward modeling of seismic records)

<matlab程序设计与应用>教材源程序，对初学者很有用！(<Matlab programming and application> teaching material source, and is very useful for beginners! )

LM算法的MATLAB实现。Levenberg-Marquardt算法是最优化算法中的一种。最优化是寻找使得函数值最小的参数向量。(LM algorithm in MATLAB. Levenberg-Marquardt algorithm is an optimization algorithm. Optimization is to find the minimum value makes the function parameter vector.)
