基于matlab车辆车牌文字识别功能(Matlab-based vehicle license plate character recognition function)

转速反馈控制直流调速系统的仿真，该模型是转速负反馈闭环调速系统的MATLAB仿真模型(Speed feedback control DC drive system of the simulation, the model is a negative feedback loop Speed Control System of the MATLAB simulation model)

图像处理的论文，介绍数字图像处理的文献，已经一些matlab的知识(Image processing of paper, describes digital image processing literature, has some of the knowledge of matlab)

本算法能够按照两种策略生成并绘制随机图，但是对于生成的随机图的属性分析不够完善，从代码中能够看出作者并没有完成本算法关于“平均路径长度”、“聚类系数”和“平均度”三个属性的求解。(The algorithm is able to follow two strategies to generate and draw random graph, but for the properties generated random graph analysis is not perfect, it can be seen from the code of the algorithm is not complete on the "average path length", "clustering coefficient" and "the average degree of" solving the three properties)

bpsk性能仿真，误码分析，matlab(bpsk performance simulation, error analysis, matlab)

说明：  matlab三维回旋仿真 使用了S函数，仿真时间300s，对于初学者有一定帮助(Matlab 3D gyration simulation uses s function)

matlab 信号分析详解(matlab design)

This method will try to extract the centre lines of the veins. This is done by calculating local maximum curvatures in cross-sectional profiles of a vein image. The method is supposed to be robust against varying vein widths and non-uniform brightness.

参考Matlab提供的模块建立简化的三相锁相环的仿真模型，只保留必要的步骤，如abc-dqz只计算Vq，去除频率反馈模块和自动参数调整模块等。 建立单相锁相环的计算模型  简化单相锁相环的系统结构，保留必要的PI控制器等模块  验证并讨论输入信号频率在45-65Hz变化时设计的锁相环的动静态性能  仿真并分析三相输入信号包含谐波、不平衡和直流偏移时锁相环的锁相结果(Reference Matlab provides three-phase PLL module to establish a simplified simulation model, retaining only the necessary steps, such as abc-dqz counting only Vq, remove frequency feedback module and automatic parameter adjustment module.  simulation and analysis of the three-phase input signal contains harmonics, unbalance and DC offset PLL phase-locked Results)
