bessel函数计算方法，源于matlab算法书中，比较权威(bessel function, method of calculation from the book matlab algorithm to compare the authority of)

光栅衍射的强度和条纹。光栅的光学实验中有着分光、压缩脉冲等重要作用。研究它有重要的意义。(Grating diffraction intensity and stripes. Spectral the grating optical experiments have, the compressed pulse an important role. Research it has important significance.)

仿真滚动轴承信号，通过不同阈值降噪方法，降噪后的时域图(Simulation of rolling bearing signal, through the different threshold noise reduction method, time-domain figure after noise reduction)

利用matlab将帧视频嵌入水印，实现效果良好。(Video frames using matlab to embed a watermark to achieve good results.)

matlab 的simulink快速入门，老师总结的，对初学者很有帮助( learning of simulink)

some code for numerical analysis.The main goal is to provide insight into numerical analysis rather than merely to provide numerical recipes.

本代码是光子晶体光纤切面的光强分布仿真程序，对搞光子晶体的同行很有帮助。(the code is photonic crystal fiber plane, the intensity distribution simulation program to engage in peer photonic crystal helpful.)

说明：  SVG仿真，运行在simulink环境下，接单相负载。(SVG simulation, running in simulink environment, single-phase load.)

这是关于永磁同步电机的直接转矩控制的程序，而且经过验证，肯定能用。也可作为参考。(This is about the permanent magnet synchronous motor direct torque control procedures, and proven, certainly can. Can also be used as reference.)
