说明：  针对污水处理系统的多变量、非线性、时变性与随机性等特点，介绍了专家系统的结构和特点及其在污水处理领域的应用研究现状，分析了其存在的问题。结果表明，国外专家系统发展迅速，并且应用领域遍及污水处理系统的各个方面，国内尚处于起步阶段。最后提出了在污水处理领域专家系统应用研究的发展方向。(Sewage treatment system for multi-variable, nonlinear, time variability and random other peculiarity of the structure and characteristics of expert systems and its application of sewage processing status, and analyzes its problems. The results show that the rapid development of foreign expert systems, and applications across all aspects of sewage treatment system, domestic still in its infancy. Finally, an expert in the field of wastewater treatment system application development direction.)

对采集到的信号进行快速傅里叶变换，可以实现对信号频谱分析(The collected signals fast Fourier transform, spectral analysis of the signal can be achieved.)

Binary frequency shift keying

matlab绘制阵列正六边形。采用角度方法。(Draw a regular hexagon array matlab. Using the angle method.)

提供了搭建的混合动力电动汽车的模型，可以在Matalb里仿真实现。(Providing the hybrid electric vehicle models built, the simulation can be implemented in Matalb inside.)

说明：  水听器阵列数据处理算法，适用于仿真，内含多个程序(Hydrophone array data processing algorithm, suitable for simulation, contains multiple programs)

角点的计算calculate the curvature of image(calculate the curvature of image)

for MLP neural network.

说明：  read an image then draw it s 3D Histogram,include R and G or R and B or G and B. I have never found correct code of this before

在vc.net 2003中调用Matlab Builder生成的COM组件，与2005中有所不同。(in vc.net 2003 Calling Matlab Builder generated COM, 2005 was somewhat different.)
