说明：  用matlab中的FFT函数实现了正弦信号，矩形信号，和白噪声的频谱分析(FFT with matlab function in a sinusoidal signal, the rectangular signal, and white noise spectrum analysis)

动态时间规整matlb源码，相比于欧式距离更能体现相关性(Dynamic time warping matlb source, compared to the Euclidean distance to better reflect the relevance)

In this paper, we show how support vector machine (SVM) can be employed as a powerful tool for $k$-nearest neighbor (kNN) classifier. A novel multi-class dimensionality reduction approach, Discriminant Analysis via Support Vectors (SVDA), is introduced by using the SVM. The kernel mapping idea is used to derive the non-linear version, Kernel Discriminant via Support Vectors (SVKD). In SVDA, only support vectors are involved to obtain the transformation matrix. Thus, the computational complexity can be greatly reduced for kernel based feature extraction. Experiments carried out on several standard databases show a clear improvement on LDA-based recognition

说明：  IIR低通数字滤波器在MATLAB中的设计方法(Low-pass IIR digital filter design in MATLAB method)

利用matlab实现功率谱估计中的间接法，不是通过函数调用实现的，是根据算法的思想，一步一步实现的，文件夹中还有实现自相关的算法(Using matlab to achieve the indirect method of power spectrum estimation, not by function calls, is based on the idea of ​ ​ the algorithm, step by step, the folder also auto-correlation algorithm)
