使用matlab仿真OFDM。其中描述了OFDM的基本原理，含详细的公式推导过程。在文章最后附有matlab代码，并且有仿真结果可参考。(Matlab simulation using OFDM. Describes one of the basic principles of OFDM, with a detailed formula derivation process. At the last article with matlab code, and have the simulation results can be found.)

利用Matlab Excel Link实现对Excel数据的处理和更新 (The use of Matlab Excel Link to achieve Excel data processing and updating)

用matlab实现对矩阵的双三次插值算法实现(Bicubic interpolation matlab realize)

边缘是指图像中像素灰度有阶跃变化或屋顶状变化的那些像素的集合。学会并掌握使用matlab进行图像的边缘检测，设计用户界面实现上述功能。 实际问题： 1、采用matlab Guide设计图像界面，可以读入并显示图像，设计实现以下功能的菜单，点击相应的菜单（如radio button）在图像界面上可以显示相应的功能。 2 使用sobel检测算子； 3 使用prewitt检测算子； 4 使用canny检测算子； (Edge is refers to the image pixel has a step change in the collection of those pixels or roof shape change. Learn and master using matlab for image edge detection, design the user interface to realize the function. The real problem: 1, Guide design based on matlab image interface, can be read and displayed image, design and implement the following function menu, click on the corresponding menu (such as a radio button) in the image on the interface can display the corresponding function. 2 use the sobel detection operator 3 use prewitt detection operator 4 use the canny detection operator )

说明：  使用的是2019a 的matlab，对海温数据进行的eof程序分析(the eof of the matlab)

用matlab实现lagrange和Newton插值方法(Achieved with matlab lagrange interpolation and Newton)

说明：  人工神经网络在数模混合电路故障诊断中的应用(Artificial Neural Networks in mixed digital-analog circuit fault diagnosis)

求解Chen系统的最大lyapunov指数。求解方法为定义法。两条相轨线的步长为初设距离d0的基础上加上相对分量。求解时直接运行chen_lyapunov.m即可。可移植性强，比如换求其他系统的最大lyapunov指数，只需要改变变量数目，方程即可。(Solving the maximum lyapunov index Chen system. Solving method for defining method. Plus the relative weight of the two basic steps of the phase trajectories for the preliminary design of the distance d0. Can be run directly chen_lyapunov.m solving. Portability, such as changing the index for the largest lyapunov other systems, you only need to change the number of variables, the equation can be.)

说明：  MATLAB编程用两种方法模拟光学实验.单缝衍射、杨氏双缝干涉、黑白光栅衍射的计算机模拟；以及用傅立叶变换方法对简单孔径衍射、黑白光栅及正弦光栅夫琅和费衍射的模拟(MATLAB program to simulate the optical in two experiments. Single slit diffraction, Young' s double slit, diffraction grating computer simulation of black and white and Fourier transform method with a simple aperture diffraction, black and white grating and sinusoidal grating Fraunhofer diffraction simulation)

关于图像的灰度处理，翻转，很不错的源码还有界面。(On the gray image processing, flip, very good source are the interface.)
