用matlab编程来实现，用HMM模型进行孤立词的语音识别(using Matlab programming to achieve with HMM term isolation of Speech Recognition)

该程序是使用Matlab仿真协同通信的DF（解码转发）基本性能，基本模型S-R-D三个节点，接收端使用MRC（最大比合并）。固定DF由于SR信道的错误，其性能受到限制，在大SNR情况下不能获得有效分集。而当SR距离足够近的时候，可能获得一定的分集增益(The program is a cooperative communication using Matlab simulation DF (decode forwarding) basic performance, the basic model of the SRD three nodes, the receiver uses the MRC (maximum ratio combining). Fixed DF error of the SR channel, its performance is limited, can not obtain a valid diversity in the large SNR case. When the SR close enough, you may get a certain amount of diversity gain)

岩石物理模型建模的另一种方法，同样可以翻译弹性参数与物性参数间的关系。(Another method of rock physics modeling, the same can translation parameters and physical parameters of elastic)

一本关于Matlab仿真通信系统的书，很系统全面地讲解了各个通信系统部分，及其matlab仿真，并附有相应的Matlab练习题。(a book about simulating communication systems using matlab. Very comprehensive explanation and corresponding matlab code, and exercises.)

通信网络课程常用Matlab算法，包括Dijkstra, Floyed,Kruskal,Prim,MaxFlowLabeling以及相关的矩阵转换和节点处理程序(Dijkstra,Floyed,Kruskal,Prim,MaxFlowLabeling and so forth)

说明：  matlab中文帮助文档，方便读者理解阅读matlab，一般的安装软件中的帮助文档是英文的，使用不方便(matlab Chinese help docment, support read convience and help you understand clearly )

改程序为matlab实现离散信号的傅里叶变换 里面有注释以供初学者参考(The program for matlab discrete signal of Fourier transformation have comments for beginners in reference )

非常实用matlab编程教程。从安装到函数应用以及可视化都有涉及。(Very practical matlab programming tutorials. From installation to function application and visualization are involved.)

Extracting MFCC features for audio files and removing silence them. Then calculating some statistical functions

说明：  电力市场的最优化分配问题源代码,电气工程同学大作业。(Optimal electricity market distribution source code, electrical engineering students to major operations.)
