Floyd求最短路

光伏并网逆变器控制技术的研究,详细分析了并网的技术难点和技术攻关。(Research on photovoltaic grid connected inverter control technology, a detailed analysis of the technical difficulties and technical problems of grid. )

Code to simulate QAM modulation and demodulation. Also has an AWGN function to add noise to symbols. A Rayleigh and Rice process are added as a part to simulate a complete communication system and uate its behavior.

说明：  常用的matlab代码，非线性方程组求解，基本可以满足大学和研究生常用代码(Common Mathematical Codes)

说明：  蚁群算法是模拟蚁群觅食行为的一种优化算法。在整个觅食过程中蚂蚁散播信息素，蚂蚁通过感知到的信息素多少，来决定所要选择的下一个栅格。蚁群算法的核心部分在于模拟了蚁群的转移概率选择行为，通过使用信息素和启发式函数值进行转移概率计算。粒子群算法可以用于机器人运动轨迹规划，求得最短路径(Ant colony algorithm is an optimization algorithm to simulate foraging behavior of ant colony.The ant disperses pheromones throughout the foraging process. The ant senses how many pheromones it has to choose the next grid.The core part of ant colony algorithm is to simulate the transfer probability selection behavior of ant colony and calculate the transfer probability by using pheromones and heuristic function values.Particle swarm optimization (pso) can be used for robot trajectory planning to obtain the shortest path)

说明：  三自由度汽车模型的Simulink模块。。。。。。。。。。。。。。。。。。(Simulink module of three-degree-of-freedom car model)

这个matlab代码 根据2012年hong的An Improved Reversible Data Hiding in Encrypted Images Using Side Match这篇算法编写而成，

说明：  matlab 实现最短路径的DIJKSTRA算法，关于图论的(matlab DIJKSTRA algorithm to achieve the shortest path on graph theory)

由于大地的吸收作用,使得地震信号高频成分损失,造成分辨率下降,因而,合理地补偿地震信号的高频成分是提高其分辨率的根本方法之一。谱白化方法是高频补偿的一种有效手段,其基本方法是将地震信号进行傅里叶变换,由时间域变到频率域;再在有效的频率范围内进行频率补偿,然后进行傅里叶反变换,由频率域变到时间域.
