matlab学习书籍，对于初学者特别有用。(matlab learning books, particularly useful for beginners.)

冈萨雷斯数字图像处理的所有matlab源码，非常全的一个，供大家对着课本学习使用。强烈推荐给大家。那本书也写的非常不错。(Gonzalez digital image processing matlab source code for all, a very wide one, for everyone to learn to use against the textbook. Strongly recommend to everyone. That book also write very good.)

用于计算两个一维向量的互信息,information.m用于计算互信息值，需要调用histogram2.m(Use for calculating the mutual information with two one-dimensional vector.)

Euler方法求解微分方程的源程序，很实用，绝对正确，还有画图功能，图形中描出点来，简单易懂。(Euler method for solving differential equations of the source, very practical, absolutely right, there are drawing function, points to delineate the graphic, easy to understand.)

说明：  matlab 实现的蚁群算法,算法经过测试，用于非线性方程的优化求最值。(the implemention of anta algrithm by mtalab)

aircraft longitudinal dynamics evaluation code for matlab. the code has been extracted from a book on aircraft stability and control. unfortunately the exact name of the book is not known.

重要参数的提取，滤波求和方式实现宽带波束形成，包括最小二乘法、SVM、神经网络、1_k近邻法。( Extract important parameters, Filtering summation way broadband beamforming, Including the least squares method, the SVM, neural networks, 1 _k neighbor method.)
