胡广书《数字信号处理-理论，算法和实现》第二版光盘内容，覆盖所有章节课后习题内容(Hu Guang book " Digital Signal Processing- theory, algorithms and implementation," Second Edition CD-ROM content, covering all sections of the content of after-school exercise)

On the companion website, you will find in the directory Chap exercises/chapter3 a workspace ex3M1.mat. Load this workspace and plot the speech waveform labeled speech1 10k. This speech segment was taken a vowel sound that is approximately periodic, 25 ms in duration, and sampled at 10000 samples/s.

K-SVD可以看做K-means的一种泛化形式，K-means算法总每个信号量只能用一个原子来近似表示，而K-SVD中每个信号是用多个原子的线性组合来表示的。 K-SVD通过构建字典来对数据进行稀疏表示，经常用于图像压缩、编码、分类等应用。(K-SVD can be regarded as a generalized form of K-means. The total K-means algorithm can only approximate one signal for each semaphore, and each signal in K-SVD is a linear combination of multiple atoms To express. K-SVD through the construction of the dictionary to sparse data representation, often used for image compression, encoding, classification and other applications.)
