该代码采用matlab和C混合编写，是采用随机梯度的方法训练线性分类器，它可用于数据、图像等的多类分类情况。参考论文：Good Practice in Large-Scale Learning for Image Classification(This a Stochastic Gradient Descent algorithm used to train linear multiclass classifiers. It is biased towards large classification problems (many classes, many examples, high dimensional data).)

用于产生巴克码序列的matlab程序，测试可以运行，解压后在matlab中打开m文件即可(Barker code used to generate the sequence matlab program, tests can be run to open the file in matlab m extract after)

三维核密度估计法的设计与实现，需要的请自行下载(Design and implementation of a three-dimensional kernel density estimation method, please download their own needs)

用MATLAB实现了CT平行束滤波反投影和扇束滤波反投影重建过程，效果良好，其中radon变换的方法采用步长法求解，较新颖。(CT achieved using MATLAB parallel beam filtered back projection and fan-beam filtered back projection reconstruction process, to good effect, in which radon transform method using step method to solve, relatively new.)

说明：  结合李银斌同学的论文第三章，得到NUFFT算法。zl为非均匀采样值，xl为非均匀网格点，ul为与xl最近的均匀网格点。得到的zk为，均匀频谱(Non-uniform fast Fourier transform)
