说明：  离散信号MATLAB分析的好程序！分析细致，有助于学习！频谱细化(MATLAB analysis of discrete signal a good program! Detailed analysis will help to learn! Spectrum refinement)

在Matlab的统计和优化工具箱中有相关的处理函数(We begin our tour of MATLAB by considering the basic structure of the user interface. We’ll learn how to enter commands, create fi les, and do other sorts of mundane tasks that we’ll need to know before we can tackle solving mathematics problems.)

信号数据预处理程序，包括低通滤波，带通滤波(Signal data preprocessor：including a low pass filter, band-pass filter)

energy efficiency when wireless body area sensor node communicates to the coordinator through wireless link when distance between the nodes are varied

These are some basic matlab codes.

Matlab能够通过sound函数来实现演奏歌曲，而且音调的高低是和频率有关，所以我们在进行音乐合成时需按音调来查所对应的频率，再按曲谱控制节奏长度，再利用sound函数播放由不同频率的正弦波合成的声音，于是就可以利用Matlab演奏歌曲了。(Music synthesis)
