节点收缩法Matlab代码

用于模拟B级路面不平度及功率谱密度曲线，可更改参数和车速，模拟不同级别的路面谱(Simulation of B grade road roughness and power spectral density curve)

找出只出现一次的数字，其他数字均出现了2次，时间空间尽量少(Identify only appears once, while other figures have appeared two times to minimize time and space)

说明：  定时时间可设置，7219显示，输出开关量信号(Timing time can be set, 7219 display, output switching signal)

说明：  虚拟同步机技术是将分布式电源、电动汽车、储能以及负荷变流器模拟为旋转同步机的技术，使得电力电子变流器能够像同步机一样具有大电网的同步机制，从而实现电力系统的自主运行。虚拟同步机技术为解决集中式风光消纳、大规模分布式能源、电动汽车和储能为电力系统带来的一系列挑战提供了一条崭新的思路和解决方案。(Virtual synchronous machine technology is a technology that simulates distributed power supply, electric vehicle, energy storage and load converter as rotary synchronous machine. It makes power electronic converter have synchronization mechanism of large power grid like synchronous machine, so as to realize the autonomous operation of power system. Virtual synchronous machine (VSM) technology provides a new way of thinking and solution to a series of challenges brought by centralized solar energy absorption, large-scale distributed energy, electric vehicles and energy storage for power system.)

说明：  一款用Qt编写的学生管理系统程序，可实现录入、存储、查询等功能。(A student management system program written in Qt, which can implement functions such as entry, storage, and query.)

ZLayoutManager-五行代码实现 炫动滑动 卡片层叠布局(ZLayoutManager-Five-Line Code for Flashing Sliding Card Layout)

对于图象处理,参数设置是一个非常重要的环节.这个代码可以借鉴一下-For image processing, parameter setting is a very important link. This code can learn from you

图书管理系统，vb制作，源代码-library management system, vb production, the source code

软件锁相环的函数想实现，用MATLAB写的，跟踪相位成功，互相学习使用，在电网电压上应用(Software phase-locked loop function to achieve, written in MATLAB, tracking phase is successful, learn from each other, used in the grid voltage)
