Gini系数典线拟合算法,包含传统数值方法与曲线拟合法比较!(Gini coefficient calculation!)

眼睛图像虹膜区域提取，内附简单说明。采用粗精双重定位。(iris recognize)

说明：  这些说明包括了该课程的数值部分上半年AMAT3122数学 微分方程的方法。他们不是一个完整的笔记。(MATLAB (MATrix LABoratory) is a very powerful package designed for numerical analysis, matrix calculations and visualisation (as well as many other applications). One of MATLABs strengths is that it can be used as a simple ‘calculator’ and also is easy to program more complicated tasks. Many mathematical algorithms are already built in to MATLAB and many more are easily added)

说明：  可以很好的结合现有的信号数据进行分析和处理，得到一定优化效果(Can be a good combination of existing data analysis and signal processing, to a certain optimal results)

关于蝶形宽带微带天线的设计 索引：蝶形宽带微带天线. 设计方案 排列效率 摘要：现在提出一种基于绝缘体衬底的有限长度的宽带微带天线的设计方法。这种方法快速、对计算精度要求较低，是建立在一蝶形天线进行二等分而形成的两个梯形天线的 。首先设计出单边的梯形部分，然后制作出相同的另一部分并在其顶点处将其连接。与理论计算相比在X波段上实验测量表现得很好。其有效带宽达到10.6％。 (One approach to an antenna book starts with a discussion of how antennas radiate. Beginning with Maxwell’s equations, we derive electromagnetic waves. After that lengthy discussion, which contains a lot of mathematics, we discuss how these waves excite currents on conductors. The second half of the story is that currents radiate and produce electromagnetic waves. You may already have studied that subject, or if you wish to further your background, consult books on electromagnetics.The study of electromagnetics gives insight into the mathematics describing antenna radiation and provides the rigor to prevent mistakes. We skip the discussion of those equations and move directly to practical aspects. )

MATLAB遗传算法工具箱，希望能对学习这方面知识的朋友有帮助。(MATLAB genetic algorithm toolbox, hoping to study in this area of knowledge has to help a friend.)

自适应中的牛顿法。结论，当u靠近0.5时，wk 迅速增加到最佳权， 当u小于0.5时，wk 沿着一个方向单向靠近最佳权；u大于0.5时wk沿着起始点指向最佳权的方向左右振荡并向最佳权收敛 ！ (The Newton method adaptive. Conclusion, when u close to 0.5, wk quickly right to the best, when u is less than 0.5, wk along the a direction close to the best the right way u greater than 0.5 wk point along the starting point about the best direction for the right to the right of oscillation and convergence of the best!)

说明：  自适应遗传算法matlab代码，用MATLAB语言编写，可以直接运行。(Adaptive genetic algorithm matlab code, used MATLAB language, you can directly run.)
