说明：  对心音信号实现平均周期图法功率谱估计的matlab程序(PSD bartlett matlab)

EMD经典程序包，求瞬时频率和瞬时幅值，以及希尔伯特谱等。(Classic EMD program package, and instantaneous frequency and amplitude, as well as Hilbert spectrometer.)

灰色按扭激活--可以将一些软件限制的灰色按扭激活使用,比如某些软件普通会员会限制一些功能,有这个就可以解开限制(Gray button activation- can be some of the limitations of the gray button to activate the software to use, such as some software will limit some features of ordinary members, have this limit can be solved)

这是学习matlab的资料，还可以的，希望对大家有帮助。(This is a learning matlab information, but also hope to have everyone help.)

说明：  以上是MATLAB编写的一些程序，用于产生一些基本的信号。(prepared by the procedures used to produce some of the basic signal.)

遗传算法的简单例子，matlab的.m文件(genetic algorithm)

支持向量机（SVM）主成分分析法进行预处理筛选变量( support vector machine (SVM)，PCA(principal component analysis))

这个程序描述了MHD激波罐问题，是用python编写的，我也看得不多(Thus in the numerical approximation rounding errors and discretization errors may lead to a violation of conser- vation)

文件里包括了扩频系统中所需的gold码序列的产生。(File system, including the spread spectrum code sequence required to produce gold.)

以Matlab为应用背景，比较详细地介绍了根轨迹图的制作。(Examples on Root Locus Plot.)
