the problem Matlab.pdf 这是个对于初学者很有用的 希望大家都能学好matlab(the problem Matlab.pdf This is very useful for beginners I hope people will learn matlab)

一些关于matlab的书，，，很有用的，，(Some of the book about matlab,,, very useful,)

混沌吸引子，有logistic,有lonez等(Chaotic attractor, there are logistic, etc. have lonez)

Example to with crypto providers containers

method for all real roots of the polynomial lab

心电信号产生程序 仿真人体正常状态下的心电信号(ECG simulation of the human body have a procedure under normal ECG)

利用matlab 实现了人脸识别，其中有矩的使用和矩的识别(code of face recognize using moment implented with matlab)

主要讨论获得图片后如何提取其边界信息,首先利用图像灰度均匀化解决了对比度不清晰的问题,然后利用高斯滤波法对图片进行滤波去噪,进而利用Canny算法实现边缘检测提取边界,该方法与Matlab自带的求边界方法有明显的提高,为利用Matlab程序求图像分形维数提供了更精确的前提. 更多还原 (Mainly discuss how to get the picture after extracting its boundary information, the first use of the image contrast of the gray uniform solution to the problem is not clear, then use a Gaussian filtering method for image filtering noise, and then use Canny edge detection algorithm to extract the boundary, the method find boundary method comes with Matlab significantly improved procedures for the use of Matlab for image fractal dimension provides a more accurate premise. more reduction)

matlab的统计回归分析，很全面的数码库，能够解觉大部分回归问题。(matlab statistical regression analysis, it is a comprehensive digital library, able to sleep most of the reunification problem solution.)

说明：  对一副测试图像进行加各种噪声，然后进行多帧平均，中值滤波，均值滤波，维纳滤波，理想低通滤波，巴特沃斯低通，带通滤波，自适应滤波九种方法处理，并分析结果，得出各种滤波方法的优缺点。包括实验报告(Plus a pair of test images of all kinds of noise, and then multi-frame averaging, median filtering, mean filtering, Wiener filter, the ideal low-pass filter, Butterworth low-pass, band pass filtering, adaptive filtering nine kinds of approach and analyze the results, obtained the advantages and disadvantages of various filtering methods. Including the lab report)
