matlab实现车牌识别，具有较好的识别效果 (achieve matlab license plate recognition, with better identification of the effect of)

说明：  语音识别VQ全过程的matlab程序，运行测试能出结果，希望对你们有用，实在没点数才把自己压箱底的东西拿出来,呜呜(VQ whole process of speech recognition matlab program, run the test to the result, I hope helpful for you, only then it did not point out what their own bottom pressure, the hum)

银表面等离子激元SPP色散关系，参考王振林老师的《表面等离子激元的研究进展》(Silver surface plasmon dispersion relation of SPP, reference Zhenlin teacher " Surface plasmon Research Progress" )

书中给出了九个典型的自动化设计例子。展示了如何用The MathWorks和其他仿真工具，比如Simulink和Stateflow建模，以此来使自动化控制系统的设计更加便利。(This book includes nine examples that represent typical design tasks of an automotive engineer. It shows how The MathWorks modeling and simulation tools, Simulink® and Stateflow,TM facilitate the design of automotive control systems. Each example explains the principles of the physical situation, and presents the equations that represent the system. The examples show how to proceed from the physical equations to the Simulink block diagram. Once the Simulink model has been completed, we run the simulation, analyze the results, and draw conclusions from the study.)

One of Biometrics fields is face recognition & face expression recognition ... 1- In face recognition .. we need to design authentication program by training a neural network ,there are two source codes..one of them is based on Discrete Wavelet Transform with Perceptron Neural Network.. and the other based on Discrete Cosine Transform with Perceptron Neural Network ... 2- In face expression recognition .. we defined the condition of the person (nature,happiness,disgust or anger) this source code is based on Principle component analysis(PCA) .. * we need to now about digital image processing ,neural network and PCA...

该方法适用于解决阶数比较大的线性方程组，从理论上讲这种方法是收敛的，而且具有较好的可操作性(this method is suited for some complex equation)

In this paper, an implementation and dynamic modeling of a three-phase induction motor using Matlab/Simulink are presented in a step-by-step manner. The model was tested by two different ratings of a small and large induction motors. The two simulated machines have given a satisfactory response in terms of the torque and speed characteristics.

在工程应用中 经常会遇到一些复杂的非线性系统, 这些系统状态方程复杂, 难以 用数学方 法准确建模。 在这种情况下, 可以 建立 BP 神 经网 络表达这些 非 线 性系 统。 该方法把未 知 系 统看成是一个黑箱, 首先用 系 统 输入输出 数据 训 练 BP 神 经网 络, 使网 络能 够表达该未 知 函 数, 然后就可以 用训练好的 BP 神经网络预测系统输出 。 本章拟合的非线性函 数为 y = x1^2+x2^2. 。 (In engineering applications often encounter some complex nonlinear systems, which complicated the equation of state, can not be accurately modeled mathematically. In this case, BP neural network can be established to express these nonlinear systems. The method of the unknown system as a black box, the first input and output data with systematic training BP neural network, the network can express the unknown function, then you can use the trained BP neural network forecasting system output. Chapter for fitting non-linear function y = x1 ^ 2+x2 ^ 2..)

matlab主要函数全部包括，及其实用，值得拥有。(the matlab function including all its practical worth having.)

关于Vega Prime的12篇期刊论文，涉及VP多场景切换、坐标系、多通道、飞行视景仿真等问题，有相当的参考价值。(About Vega Prime' s 12 journal articles, and more scenes involving VP switching coordinates, multi-channel, flight visual simulation and other issues, there is considerable reference value.)
