很有用的时频分析工具，内附各个函数的说明，方便调用。(Very useful tool for time-frequency analysis, containing a description of each function, easy call.)

MATLAB 实现拉格朗日插值算法 (Lagrange interpolation algorithm in MATLAB)

基于PCA降维的k-means算法，附带有检测正确率的源码以及相应的检测数据(PCA dimensionality reduction based on k-means algorithm, source code comes with the correct detection rate and the corresponding test data)

Corner detection for camera calibration using a 3D calibration object. To get corners one must to define a 6point ROI. The corners will be detected inside ROI and will be put into a vector.

卷积码是一种有记忆的编码，在任意给定的时间单元处，编码器的n个输出不仅与此时间单元的k个输入有关，而且也与前m个输入有关。卷积码通常表示为：（n,k,m） 本次仿真采用（2，1，3）卷积码。 (convolutional code is a kind of code memory, in any given unit of time, the encoder output n this time not only with the elements of the k input, but also with the input m. Convolutional codes are usually stated as : (n, k, m), the simulation used (2,1,3) convolutional code.)

带阻滤波器，包括程序和一个实例，程序每句都有注释，这样更加易懂(Bandstop filter comprising an instance of the program, and the program has a comment sentence, so more understandable)
