surg voltage in matlab

利用matlab里面的吹风机数据，用前300个数据进行辨识。分别采用最小二乘辨识和相关性系数法辨识。并画出图形。通过对比最小二乘法和相关函数两种方法得出来的辨识图形。可知相关函数辨识的准确度更高。(Use a hair dryer inside matlab data before using 300 data identification. Were used to identify the least squares identification and correlation coefficient method. And draw graphics. By comparing the least squares method and related functions have two ways out of the identification graphics. Shows a higher correlation function identification accuracy.)

DigiPic 函数主要功能是将一个图片形式的表格函数,获取其数据,拟合为一个解析式. 便于计算机使用 DigiPic功能描述 在matlab 2013a运行环境下,启动DigiPic 首先,导入要分析的图表照片 取点建立坐标系,坐标系在取点时同时输入对应的实际坐标值, 拖拽坐标点使其位置在图片上尽量准确,便于后面坐标的自动计算. 按右键完成坐标系的建立. 在图片上原函数图线处取点.同时自动计算函数值 在拟合页,导入函数数据.选择相应的拟合函数.自动计算出最佳参数. 在拟合前,可人工在函数列表中修改,设定参赛,使计算更快. 选择保存目录,保存数据.数据以excel文件保存,图片和数据文件最好放在一个目录里. excel文件数据可直接在其它分析软件中使用. 打开原分析文件时,可同时打开多个.( DigiPic function main function is to form an image in the form of a function, to get their data, fitting of an analytical style. To facilitate computer use DigiPic Description operating environment in matlab 2013a, start DigiPic First, import to be analyzed Charts Photos access point to establish a coordinate system, the coordinate system at the access point simultaneously enter the actual coordinate values ​ ​ corresponding to the coordinates of the point drag on the image to make it as accurate as possible location, easy to automatically calculate the coordinates back. completed by the right coordinates established. Uehara function graph in the picture at the access point. while automatically calculated in the fitting function value page data import function. choose the appropriate fitting function. automatically calculate the optimal parameters. before fitting, artificial modification in the function list, set the entry to make computing faster. choose to save)

图像的哈弗曼编码matlab实现，实现图像的无损压缩(Matlab coding huffman images achieved)

说明：  用Matlab编写的用Kalman滤波方法估计目标航迹的程序，有详细注释，是学习Kalman滤波方法的好材料(Written with Matlab using Kalman filter to estimate target track of the process, detailed notes, is a good learning materials for Kalman filter)

把遗传算法和退火算法相结合，寻找图像分析所需的阈值。(genetic algorithms and annealing algorithm combining image analysis to find the required threshold.)

直扩系统传统DMF解扩SIMULINK建模(DS system, the traditional DMF despreading SIMULINK modeling)

子空间法计算DOA AOA，ESPRIT旋转不变法程序(Subspace method DOA AOA, ESPRIT rotation invariant method program)

这个程序是用在LDPC加EM中的，自己编的有很好的性能，用来估计依稀未知的参数，比如相偏频偏之类的(This procedure is used in LDPC EM in Canada, his series have good performance, used to estimate the unknown parameters vaguely, such as phase offset of the class of partial)

通过二维图抽象的DCT变换，取前n和系数进行重构得到的图像进行显示(Two-dimensional map by abstraction of DCT, take the first coefficient n and displays the image reconstructed by)
