This is a code for a Chebyschef filter

该程序实现了压缩感知理论中采用矩阵的优化。在压缩感知理论中，要求采样矩阵与稀疏矩阵的相关性越低越好。该代码采用一种交替投影的方法实现采用矩阵的优化，有效降低其相关性。(The program to achieve the optimization of the use of matrix theory compressed sensing. Requirements of the sample matrix and sparse matrix theory of compressed sensing, the lower the better. The code uses an alternating projection method to achieve the optimization of the use of matrix to effectively reduce the correlation.)

根据所给定的节点值和节点上的函数值,取边界条件为 “左右两端的一阶导数值为零”, 编制构造三次样条函数的 Matlab 程序。 另附测试程序(Depending on the value of a given node and the node function value, taking the boundary conditions for the " right and left ends of the first derivative value of zero," the preparation of structural cubic spline function of Matlab procedures. Attached test program)

实现物种功能的语音处理：倒谱、时域、频谱、语谱图以及功率谱，并加有详尽的注释。另外还可以保存图像，一倍后来研究！matlab ＧＵＩ编程(Voice processing functions to achieve species: cepstrum, time domain, frequency spectrum, spectrogram and power spectrum, and add detailed comments. It also can save the image, doubled and later research!)

对数字信号的波形及其频谱分析，着重比较其在时域和频域上的差别(Digital signal waveform and its spectrum analysis, focused on comparative differences in the time domain and frequency domain)
