验证在时域AWGN添加的SNR的数值等于在频域获得的SNR数值(Validation added in the time domain SNR value equal to access to the SNR in the frequency domain values)

该程序利用希尔伯特变换求解心音信号的包络(hilbert envelope)

这是关于图论的内容，用于获得两点间的所有路径。(get path of two nodes)

使用ziegler函数可以直接设计出系统的PID类控制器(ziegler function can be used directly to design the PID controller category)

基于matlab的GPC广义预测控制算法。其中使用fminunc函数求解性能指标，而没采用传统的解析解法。(based on matlab gpc solution. function fminumc is used to sovle J， without troditionnal funtion)

从物理的角度看，音乐是不同频率，不同时长声波的组合，声波的频率表示不同的音调，声波的时长反映不同的节奏，根据该原理，将不同频率，不同时长的声波进行有序组合，则能成为音乐，利用MATLAB对不同频路信号的组合及分析功能，能够进行简单的音乐合成。(From a physical point of view, the music is different frequencies, not at the same time the combination of the long acoustic wave, the frequency of the acoustic wave which means that a different tone, sound waves reflect the length of time the type of rhythm, based on the principle of different frequencies, not at the same time long waves are conducted orderly composition, to become the music, using MATLAB combination of signals of different frequencies Road and analysis capabilities, able to perform simple music synthesizer.)
