此乃用MATLAB进行PFC（功率因数校正）的simulink模型，对PFC的建模，非线性分析和参数设定具有重要作用！(This is to use MATLAB to PFC (Power Factor Correction) in simulink model of PFC modeling, nonlinear analysis, and parameter setting plays an important role!)

基于MATLAB的处理图像的颜色灰度归一化的部分代码，需要的同志请下载。(MATLAB-based image processing color gray normalized part of the code, comrades need to download.)

分别在2幅灰度图像中加入一定量的高斯噪声和椒盐噪声，噪声强度自定。然后采用3×3的均值滤波器和3×3中值滤波器分别对噪声图像进行处理，给出两种处理方法的峰值信噪比(PSNR)；仿效“中值滤波”的方法，对原图像分别进行“极大值滤波”和“极小值滤波”，对所形成的图像给出说明。(Two gray-scale images a certain amount of Gaussian noise and salt and pepper noise , noise intensity since .)

matlab编写基于循环平稳谱估计的认知无线电频谱感程序。(matlab to prepare a smooth spectrum estimation based on the cycle of the radio spectrum of the cognitive sense of the procedure.)

一个用MATLAB编写的优化控制工具箱，非常实用(a prepared using MATLAB Toolbox optimal control, very practical)

关于kalman滤波的一个比较有代表性的例子，程序中把没有加高斯噪声和加过高斯噪声后进行滤波后的图形用不同颜色的曲线画在了一个图上，便于比较和理解(Kalman filter on a more representative example of the program to add Gaussian noise and processing not been filtered Gaussian noise after the graphic curves of different colors painted on a map, to facilitate comparison and understanding)

Abstract—In this paper, a new lossy technique based on wavelet transform for compression of breast ultrasound images is presented. The experiments are performed on 16 different wavelet functions and the quality of reconstructed images is evaluated by using Compression Ratio (CR), Normalized Mean Square Error (NMSE), Normalized Absolute Error (NAE), and Peak Signal to Noise Ratio (PSNR) criterion. An ultrasonographer performed the subjective assessment. This study shows that among the utilized wavelets,

使用matlab完成harris corner检测，探测出边界点(Use matlab completed harris corner detection, detection of boundary points)

北大医学部（医学统计学）的课件，里面重点讲解实验数据统计，方差分析，相关与偏相关等方法，这是不确定性实验数据统计必修方法，使用matlab的同学有福了。(PUHSC (Medical Statistics) courseware, which highlight the experimental statistics, analysis of variance, correlation and partial correlation method, which is the uncertainty of experimental data statistics compulsory methods, the use of matlab student blessed.)

层次分析中确定权重的方法，主要是针对聚类中没有出现交叉情况下确定权重(The level of analysis to determine the weight of the method, is mainly directed against cross-clustering does not appear to determine the weight of circumstances)
