利用非线性控制完成光伏并网逆变器的设计，设计中采用模糊控制和反步法，介绍很好。(Using nonlinear control to complete the design of the photovoltaic (pv) grid inverter, adopted in the design of advanced reverse moves, the introduction is very good.)

运用Matlab仿真工具，结合机械臂运运动学特性，实现了机械臂系统的运动学仿真。 (Use the Matlab simulation tools, combined with the kinematic characteristics of the robotic arm transported the kinematics of the manipulator system simulation.)

利用matlab模拟光纤中EH11模的模式分布图。(Using matlab simulation mode fiber EH11 mode maps.)

说明：  多功能史密斯圆图，带单枝节，双枝节匹配，有动态演示效果。各种参数可调。程序调通了，没问题。(Multifunctional Smith map, with single side, double side match, the effect of dynamic presentation. Adjustable parameters. Transfer procedures had, no problem.)

gabor 小波matlab变换,与C结合(gabor wavelet transform matlab, and C combined)

对文本文件进行huffman编码，并显示huffman树(to the text document for Huffman coding, and that Huffman tree)

说明：  分布式编码代码 C语言的，很多行，如果要用Matlab编应该有些参考价值。(distributed coding)

原创的，使用vc++实现匀速运动模型（constant velocity）的kalman滤波，可以运行，并有matlab测试程序对滤波结果进行对比。(vc++ constant velocity kalman filter。the matlab m file can obervers the filter results)

详细介绍了MATLBA中的COV函数的使用和作用(Introduces the use of MATLBA COV function and role )

LDA知识的讲解，浅显易懂，便于学习，还有对LDA模型的建立的说明以运用(LDA knowledge to explain, easy to understand, easy to learn, as well as the establishment of LDA model description to use)
