lingo 程序，解决线性规划和非线性规划问题，这里主要介绍物资需求计划模型的程序(lingo（demand and supply）)

说明：  matlab格式源代码。功能：利用改进遗传优化算法解决BP神经网络中局部最小问题。(matlab source code format. Function: the use of improved genetic optimization algorithm BP neural network to solve local minimum problems.)

改进了BIHT中的观测矩阵，实验结果证明，误差更小了(change the measurement matix,result better)

matlab 代码 机器学习算法 决策树算法id3算法 (matlab id3 算法)

这是用Matlab写的m文件，实现图片灰度变换功能，具体功能和操作在程序中有详细说明(It is written with Matlab m file functions to achieve image gray-scale transformation, the specific functions and operations are detailed in the program)

用matlab编的基于水平集的图像分割.m文件(Matlab code using level set based image segmentation. M file)

simple recurrent networks

object-oriented programming

k-d树的matlab程序，包含了KDTREE, KDTREEIDX and KDRANGEQUERY functions。提供了两个Demo scripts(kdtree_demo.m & kdrange_demo.m),很实用( This distribution contains the KDTREE, KDTREEIDX and KDRANGEQUERY functions. Included are the source code files in kdtree/src, as well as precompiled mex files for the following systems: - Mac OS X (Matlab 6.5) - Redhat Linux (Matlab 6.5) - Windows (Matlab 6.1) Two demo scripts are provided (kdtree_demo.m & kdrange_demo.m). The new features added June 2004: + You can now use N dimensional data points, where N>3. + Use KDTREEIND to return the index value to the closest point, instead of the closest point values. + KDRANGEQUERY can now return these index values as well.

直方图均衡化，适用于matlab对某一幅特定图像的增强处理(Histogram equalization, apply a matlab for a specific image enhancement processing)
