该压缩包里为三个test文件，里面包含了100多个MATLAB实用程序。它是初学者的入门MATLAB很不错的资料。(The compression bag for three test file, which contains more than 100 MATLAB utility. It is very good information for beginners Getting Started with MATLAB.)

说明：  基于matlab用神经网络的一组数预测，数学建模里比灰度预测好用(Een reeks nummervoorspelling op basis van matlab met behulp van een neuraal netwerk, wat beter is dan grijze voorspelling in wiskundige modellen)

RBF神经网络利用MATLAB工具箱函数实现非线性函数回归(RBF neural network using MATLAB toolbox function is to achieve non-linear regression function)

介绍了平均电流控制型 PFC Boost 变换器的结构， 分析了其工作原理。 分别采用 Power System 工具箱和考虑电感电流断续工作状态的 C-MEX 文件 S 函数建立了主电路模型，对平均电 流控制型 PFC Boost 变换器进行了仿真。仿真结果表明，与 Power System 工具箱模型相比，基于 C-MEX 文件的 S 函数仿真模型能够准确仿真电流断续工作状态，仿真速度快。设计了电路样机进 行了实验研究，仿真结果与实验结果一致，证明了该方法的正确性。利用该方法可以高效地仿真 研究系统结构和参数变化时性能变化情况，得到的平均电流控制型 PFC Boost 变换器的混沌分岔 图，为更好地理解和设计这种变换器提供了有利的工具。(The structure of average current controlled power factor correction (PFC) Boost converter is introduced, and its working principle is analyzed. The PFC Boost converter is simulated using the model established with Power System toolbox and the C-MEX file S-function model respectively. Simulation results show that the C-MEX file S-function model can simulate the all state of the converter including discontinuous conduction mode with high speed. Experimental results show the correctness of the simulation results and the proposed method. The method is suitable for simulation the performance changing with the variation of system structure or parameters. The bifurcation diagram is derived for PFC Boost converter using this method, which is very useful for better understanding and better design of the converter.)

利用matlab进行信号处理的几个例子，简洁明了，十分实用(examples about signal processing using matlab)

对图像进行逐点计算，并且取最大值和最小值的差值作为该点新的灰度值。 在区别边缘点和非边缘点时，首先确定一个阈值T，若图像中像素点的新 值大于该门限值，则可以初步确定为边缘点，小于T的新值被判断为非边缘点.(Image point by point basis, and taking the maximum and minimum points of difference as the new gray value. Edge in the difference between point and non-edge point, first determine a threshold T, if the image of the new pixel value is greater than the threshold, you can initially identified as the edge point, the new value is less than T have been judged as non-edge point.)
