创建一个first order 低通模拟信号滤波器。输入为热噪音(creative a first order low pass filter, the in put is the white noise.)

一个增强版的遗传算法，用于波束赋形，可供初学者学习使用。(An enhanced version of the genetic algorithm for beamforming, for beginners to learn to use.)

matlab 基本语句描述，及一些基本内部函数，很有用的，欢迎共享，谢谢(Differential evolution algorithm is very popular in recentyears, it iswidely used in complex optimi- zation questionsbecause of it’s easy implementation and has less controlparameters. Butconventionaldifferen- tial evolution algorithm has a problem ofstagnation thatcan stop the algorithm convergence. )

这个matlab程序实现了目标对象的图像分割与提取技术，附件里的程序以车牌的检测与识别为例，效果非常好。(The matlab program to achieve the target object' s image segmentation and extraction technology, in the annex of the procedures for license plate detection and recognition, for example, the effect was very good.)
