curvature test for fitting model.

用平面波展开法计算二维声子晶体带隙,这个有中文注释，看得明白，二维声子晶体FDTD方法计算禁带宽度的例子。( Computation Method D phononic bandgap plane wave, The Chinese have a comment, understand it, Dimensional phononic crystals FDTD method calculation examples band gap.)

激光光束在介质中传播的分析及仿真，可仿真光束传输特性，程序运行结果较为直观，(Laser beam propagation in the medium analysis and simulation, the beam transmission characteristics can be simulated, the program operating results are more intuitive,)

这是图像处理中的车牌检测，是用matlab编写实现的。(This is the license plate detection, image processing is achieved using matlab.)

基于自动细胞法的平面交叉口仿真 对平面交叉口不取消左转的仿真程序：model1.m 对平面交叉口以绕行方式取消左转的仿真程序：model2.m 对平面交叉口以迂回方式取消左转的仿真程序：model3.m (Does not abolish the intersection turn left emulator: model1.m intersection to bypass cancel turn left emulator: emulator model2.m circuitous way to cancel the intersection turn left: model3.m)

CEC09年群体智能会议的测试问题的代码(CEC09-MOEA-Codes-of-Problems matlab code)

The attached file is a tutorial on matlab that will provide the necesssary guidance to those programming in matlab.

合成孔径雷达（SAR)目标成像仿真，LCMV优化设计阵列处理信号，通过matlab代码，已调制信号计算其普相关密度，利用自然梯度算法，包括调制，解调，信噪比计算。( Synthetic Aperture Radar (SAR) imaging simulation target, LCMV optimization design array signal processing, By matlab code, Modulated signals to calculate its density Pu-related, Use of natural gradient algorithm, Includes the modulation, demodulation, signal to noise ratio calculation.)

说明：  matlab的中文帮助文档，便于学习的好资料，欢迎大家下载。。。(matlab help documentation in Chinese, easy to learn any information, welcome to download. . .)

已知指定参数值，用matlab编程实现一个滞后补偿器。已满足题目参数要求。(Known to specify parameter values, using matlab programming a lag compensator. Parameter requirements have been met subject.)
