功率谱估计基本算法，包括Bartlett，welch等(Power spectrum estimation)

数值分析的非线性方程组的解法，工具使用的是matlab，很简单但很实用。(Numerical analysis of nonlinear equations, solution, tool use matlab, very simple but very practical.)

将core.txt文件放在C盘根目录下,然后打开matlab，点击“文件”-“打开”选中main.m文件，“运行”这个文件。 命令窗口马上就会显示出运行结果。 mm_Red.m为封装的盲目约简算法.返回值为约简结果. sxzyd_Red为封装的基于属性重要度约简算法.返回值为约简结果. bsjz_Red为封装的辨识矩阵约简算法.返回值为辨识矩阵和约简结果. cal_sig为封装的求属性重要度的函数。 max_min为封装的求属性度最大，划分个数最小的属性的函数。 dele_max为封装的删除属性度最大，划分个数最小的属性的函数。 mycore.m为封装的求核函数. myind为封装的求划分的函数. ind_E_a为求每个属性的划分的函数.(Files on the core.txt to the C root directory, then open matlab, click on " File" - " Open" main.m file is selected, " Run this file. The command window is displayed immediately run results. mm_Red.m the package blindly reduction algorithm. return value reduction results. sxzyd_Red degree reduction algorithm based on attributes important to package the return value is the result of the reduction. bsjz_Red matrix reduction algorithm for the identification of the package. return value identification matrix and reduction results. cal_sig package attribute importance to the function. max_min demand for the package attribute degrees largest division of the function of the minimum number of attributes. delete attribute degrees dele_max package is the largest division of the function of the minimum number of attributes. mycore.m seeking nuclear function package. myind package and by function. ind_E_a for the sake of each attribute divided function.)

三维模型数据中包含“Princeton Shape Benchmark dataset”，三维模型数据库，其中的.off文件为三维模型，这些模型可以使用文件夹中的“打开三维模型的软件”打开查看。 matlab代码中“读取三维模型”为matlab读取.off文件的代码，得到的是三角面片信息和点云坐标 “三维模型切割”中为切割三维模型的一个例子，具体是从三维模型上找三个点构成一个平面，找到这个平面与三维模型的交点，这只是一个例子，具体如何切割三维模型需要自己实现，其中读取的三维模型为.obj格式，实验时需要把这部分换成上面读取.off的代码。运行其中的cut.m和cut2.m文件 “CBSM特征提取”用于提取形状特征，a.m是批量提取的，b.m是提一张图片的(3D model data contained in the Princeton Shape Benchmark dataset , the three-dimensional model , which .off file three-dimensional models that can be used in the folder open a 3D model of software Open View. matlab code reads the three-dimensional model for the matlab code to read .off file to obtain a triangular facets information and coordinate point cloud Three-dimensional model of cutting as an example of cutting three-dimensional model, in particular to find a three-dimensional model the three points form a plane, find the intersection of the plane and three-dimensional model, this is just an example of how to cut specific need to implement three-dimensional model wherein the three-dimensional model is read .obj format, experiments need to replace this part of the above read .off code. Run one of the cut.m and cut2.m file CBSM feature extraction is used to extract the shape feature, a.m bulk extraction, b.m is to provide a picture o)

说明：  该算法主要是基因遗传优化算法，非常实用，能有效解决权值确定。(The algorithm is mainly genetic optimization algorithm is very practical, can effectively solve the right to determine the value.)
