这是模式分类一书中批处理裕量松弛算法和单样本的裕量松弛算法的matlab代码实现。pudn绝无二家。(This is a book of pattern classification margin batch relaxation algorithm and the margin of a single sample relaxation algorithm matlab code. 2 pudn no.)

用Matlab程序实现P阶Levinson-Durbin算法。以一个2阶自回归模型（参数为b0=1, a1=0, a2=0.81）和一个2阶滑动平均模型（参数为b0=1, b1=1, b2=1）为例，选取观测数据长度为1000，分别用一个AR(2)模型和一个AR(10)阶模型来估计其功率谱。设激励信号模型的高斯白噪声的均值为0，方差为1。用Levinson-Durbin算法迭代计算AR模型参数，并用估计出的AR模型参数画出观测信号的功率谱。并对Levinson-Durbin算法的性能进行分析。(Write a small MATLAB program that implements the pthorder Levinson-Durbin (L-D). Run/Test the program using a AR(2) process (b0=1,a1=0, a2=0.81) and an MA(2) (bn=1,1,1) process-about 1000 samples. Use L-D with p=2 (for the AR) and 10 (for the MA). Plot the AR spectra produced in the two cases with L-D. List the direct form and the reflection coefficients in a table. Profile the L-D (total number of computations for a pthorder)

车牌水平矫正中radon变换的应用，注意radon变换检测直线方向有几种，有基于投影最大值的，有基于车牌字符空隙的等。(The level of radon transform plate correction application, pay attention to radon transform to detect straight line there are several, with the maximum value based on the projection, there are gaps in the other characters on license plates.)

This simple Matlab function simulates a innovative algorithm for narrow band interference mitigation for wireless communications, esp for satellite comm. The algorithm looks similar to LMS, but error is non-linearly transformed. It works well and a hardware demonstration was successfully fulfilled on Altera FPGA development platform. More details on algorithm refers to "Nonlinear Techniques for Interference Suppression in Spread Spectrum Systems" by R. Vijayan.
