Hilbert_huang 变换，计算经验模态函数，求瞬时频率(Hilbert_huang transform to calculate the empirical mode function, find the instantaneous frequency)

演示MA序列的特征值、自协方差函数和谱密度。程序是开放的，可以修改参数(MA eigenvalues ​ ​ demo sequence, since covariance function and spectral density. The program is open, you can modify the parameters)

matlab编程的SAX程序，实现时间序列的离散化。(Matlab programming SAX program to realize the discretization of time series.)

communication system simulation in matlab

贝叶斯分类器 模式识别（电子工业出版社）源代码(Bayesian classifier ..........)

在FFT后信号的频率往往与谱线不相重合，而在两条谱线之间。为了要求得信号的频率、幅值和初始相角，必须要使用修正法来完成。这里给出一种修正法。(After the signal in the FFT frequency spectrum often do not coincide, and in between the two lines. Request for a signal frequency, amplitude and initial phase angle, we must use to complete the Amendment Act. Here are a Amendment Act.)

这是解三对角线性方程组的一种方法。能有效的快速求解。(This was three diagonal equations of a method. Fast effective solution.)
