关于数字图像处理的PPT，里面包含一些C++，MATLAB实现等等，对于学习数字图像处理非常有帮助(On the digital image processing PPT, contains some c++. MATLAB, and so on, to learn the digital image processing is very helpful )

核方法工具箱，包括核典型相关分析KCCA，KPLS等算法的源码和实现。(Kernel Methods Toolbox KMBOX includes implementations of algorithms such as kernel principal component analysis (KPCA), kernel canonical correlation analysis (KCCA) and kernel recursive least-squares (KRLS). )

Power quality generation of voltage sags. All kinds of sags can be generated.

一些滤波器设计方法的演示程序，包括窗函数法等，程序之中会有注释，主要是用来学习数字信号处理(Some filter design methods demonstration program, including the window function method, etc., will be among the program notes, is primarily used for learning digital signal processing)

道格拉斯-普克算法(Douglas–Peucker algorithm，亦称为拉默-道格拉斯-普克算法、迭代适应点算法、分裂与合并算法)是将曲线近似表示为一系列点，并减少点的数量的一种算法。它的优点是具有平移和旋转不变性，给定曲线与阈值后，抽样结果一定。(Douglas Peucker algorithm is the curve approximated by a series of points, and reduce the number of points of an algorithm. It has the advantages of translation and rotation invariance, given the curve and the threshold, the sampling results must.)

本次实验是要我们先产生心电信号，再加噪声再滤波。由一个心电信号数据表输出心电信号，由于已知的心电信号有噪声，所以我先将信号进行滤波，得到正确的心电信号。再加噪声，通过滤波可以得到高频和中频噪声，将原信号加上噪声显示再滤波。每次的时域信号都画出了他们相应的频谱，便于观察。每次的滤波我也尝试了不同的滤波器。(This experiment is to produce our first ECG, together with noise and then filtering. ECG data from a table output ECG, ECG as a known noise signal is filtered first, I get the correct ECG. Plus noise can be obtained by filtering high-frequency and intermediate frequency noise, the original signal plus noise shown again filtering. Time-domain signals each draw their corresponding spectrum, easy to observe. Every time I try to filter the different filters.)

说明：  基追踪算法，用于解决压缩感知问题的经典算法，使用ADMM求解。(It is a matlab version of Basis Pursuit algorithm used to solving compressed sensing problem.)
