主成分分析法的一个例子程序，在建模中应用(Principal component analysis, an example program in the modeling application)

用训练序列和lloyd算法，对一个正弦信号数据进行标量量化。(Using the training sequence and lloyd algorithm, we take a sinusoidal signal data for scalar quantization to deepen our understanding.)

利用阈值函数进行心音去噪的程序，利用了改进的双参数可调阈值函数(A threshold function is used to denoise the heart sound, and the improved dual parameter adjustable threshold function is used.)

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.)
