matlab5的使用守则，很有用呦。我看了写的还蛮详细的。大家一定要挺呀。(matlab5 the use of codes of practice, very useful Yo. I have read quite a detailed written. Rather it must be everybody.)

说明：  本程序用来求转子的临界转速，模型为有限元模型(This procedure is used to seek the rotor critical speed, the model for the finite element model)

最速下降法，优化算法的一种，具有二次收敛性，若目标函数为二次正定函数，经有限步可达到极小点(Steepest descent method, an algorithm with quadratic convergence, if the objective function is quadratic positive definite function can be achieved by the finite step minima)

底部剪力法求地震作用力 matlab 源程序(Base shear method matlab source)

也是自适应的波束形成，有中文注解,好好看，应该能看懂的(adaptive beam forming)

利用matlab程序设计出匹配滤波器的功能源码(Procedures designed to use matlab function of matched filter source)

THIS EXAMPLES CODE FOR C++

搭建了一个OFDM系统，并用基于导频的方式进行了信道的估计，最后画出了系统在3条径下的瑞利信道时误比特率随信噪比的变化。(bulid a OFDM system,make channel estimation based on pilot signal,finally,plot ber when SNR changed)

对光场相机成像过程及空间域重对焦的仿真，来自MIT,输入图像即可得到光场图像，改变聚焦参数可得到不同对焦平面上的图像(Light field image processing and refocusing)

三相光伏逆变并网的仿真，车牌识别定位程序的部分功能，实现六自由度运动学逆解算法。( Three-phase photovoltaic inverter and network simulation, Part of the license plate recognition locator feature, Six degrees of freedom to achieve inverse kinematics algorithm.)
