matlab code for 16qam modulator

说明：  提取opencart产品名称里的属性信息到目录属性里，实现opencart的目录筛选功能。具体属性需添加到文件内，具体看文件说明。(Extraction of Opencart product name in the attribute information to the directory attributes, implementation of Opencart directory screening function. The specific attributes need to add to a file, see the specific documentation. )

是本科毕设的题目，对于初学matlab的同学会有帮助，在MATLAB中求图像纹理特征。( The title of the commercial is undergraduate course you Matlab for beginner students will help, In the MATLAB image texture feature.)

c4.5 algorithm in matlab

matlabk-means聚类多维数据分析(matlabk-means clustering multidimensional data analysis)

Jerk混沌序列转换为二进制后，序列的相关性分析 程序简单运行方便(After Jerk chaotic sequence converted to binary, correlation analysis program sequences to facilitate simple operation)

说明：  100kV光伏并网平均模型 MPPT使用扰动观察法(Average Model of 100 kV Photovoltaic Grid Connection MPPT uses perturbation observation method)

运用分块算法将秘密图像嵌入的一幅大图中，达到信息隐藏的效果(Block algorithm using a secret image is embedded in a large figure, to the effect of information hiding)

说明：  自适应中值滤波器的滤波方式和传统的中值滤波器一样,都使用一个矩形区域的窗口Sxy,不同的是在滤波过程中,自适应滤波器会根据一定的设定条件改变(即增加)滤窗的大小,同时当判断滤窗中心的像素是噪声时,该值用中值代替,否则不改变其当前像素值,这样用滤波器的输出来替代像素(x,y)处(即目前滤窗中心的坐标)的值。(Adaptive Median Filter for filtering methods and the same as the traditional median filter, use a rectangular area of the window Sxy, different in the filtering process, the adaptive filter in on certain Presumed Conditions change (an increase of ) filter window size, while when the judge is the filter window center pixel noise, the median value is used instead of, or does not change its current pixel value, so that the output with a filter to replace the pixels (x, y) Office (that is, coordinates of the current filter window centered) values.)
