k近邻的两种改进算法，采用matlab实现，使得算法效率有了较大提高。(two methods for knn，both of them are run in matlat.)

结构方程中拟合函数的迭代算法，不同于PLS算法。而是采用BFGS拟牛顿法求解，得出的结果与LISREL软件结果一致. 注：此算法只是针对本人一个模型使用，不同模型要做改动(This program for solving the fit function of Strual Equation Modeling ,BFGS is using for minimize the fit function with the initial point estimated by PLS)

用matlab实现对图片的lsb算法的嵌入和提取，嵌入和提取方便简便，易懂。效率高(Using matlab to achieve the picture of the lsb embedding and extraction algorithms, embedding and extraction is simple convenient, easy to understand. High efficiency)

一个基于matlab的有限元分析程序，用三角形单元对二位有限元问题进行分析(A matlab based on the finite element analysis program, two finite element analysis using triangular elements)
