自己编写的MATLAB函数，实现对图像的旋转。B是原图像，灰度或彩色，alpha是旋转角度（角度或弧度单位均可），A是旋转后图像。旋转后图像信息尽可能不损失。(I have written MATLAB function, to achieve image rotation. B is the original image, grayscale or color, alpha is the angle of rotation (degrees or radians per unit), A is rotated images. Rotation after the image information as possible without loss.)

matlab非线性kalman滤波工具箱，包括了ukf,pf等等，很好用(nonlinear kalman filter matlab toolbox, including ukf, pf, etc., very good)

SAR成像的后向投影算法 matlab代码，直接使用，对散射数据成像 频域(back projection)

传统频谱校正方法和全相位频谱校正法比较，可以看出全相位频谱校正的优势很明显(Traditional correction method and full-spectrum phase spectrum correction method of comparison, we can see the advantages of all phase spectrum correction obviously)

仿真了雷达系统中信号产生、回波信号、脉冲压缩、MTI、MTD与恒虚警检测的过程。(Simulated radar signal generation system, the echo signal, pulse compression, the process of MTI, MTD and CFAR detection.)

求取倒频谱系数，可对声音信号进行分析，是一种特征提取方式(Obtaining cepstral coefficients, can the sound signal analysis, feature extraction is a way)

猴子摘桃海滩上有一堆桃子，五只猴子来分。第一只猴子把这堆桃子凭据分为五份，多了一个，这只 猴子把多的一个扔入海中，拿走了一份。第二只猴子把剩下的桃子又平均分成五份，又多了 一个，它同样把多的一个扔入海中，拿走了一份，第三、第四、第五只猴子都是这样做的， 问海滩上原来最少有多少个桃子？(Peach Monkeys on the beach there is a pile of peaches, five monkeys for points. The first monkey peach credentials this heap is divided into five copies, more than one, the monkey to more than one thrown into the sea, took a. The second monkey the rest of the peaches and what the average is divided into five, and there are one, and it is likewise more than one thrown into the sea, took a third, fourth, fifth monkeys are actually doing that , the question on the beach for at least the number of the original peach?)

PCA人脸识别 的源代码 在matlaB 里面实现的(PCA MatlAB FaceRec.m eigface Reconstruct.m calc xmean,sigma and its eigen decomposition)

本例用五点差分法求解一个二阶偏微分方程，其间用SSOR预处理的CG法处理，此实验可分别选取N=4，8，16，32(This example uses a five-point difference method for solving second order partial differential equations, during which the CG with SSOR pre-treatment, were selected for this experiment can be N = 4,8,16,32)

分析比较了16QAM的块状导频与没有加信道估计的性能比较OFDM系统(Analysis and comparison of 16QAM and no massive increase pilot channel estimation OFDM System Performance Comparison)
