说明：  matlab环境下图象图形处理的基本函数的介绍以及简单示例(matlab environment images deal with the basic function of graphical presentation, as well as simple examples)

MATLAB连续潮流程序（9节点） （百度百科）连续潮流需要注意的问题： 1 连续潮流中两个重要的问题是：连续参数的选择和步长的确定。参数选取不正确或是步长不合理都会导致潮流不收敛。 2 连续潮流所求出的负荷裕度是针对特定网络状态和特定的负荷增长方式而言的。当增长方式改变或是网络结构或是参数发生改变后，连续潮流求出的负荷裕度是会改变的。 3 至今为止，出现了基于负荷增长的连续潮流、基于网络断线故障的连续潮流等。 (MATLAB continuous flow program (9 nodes) (Baidu Encyclopedia) continuous flow problems that need attention: A continuous trend in two important questions are: selection and step continuous parameter determining long. Parameter selection is incorrect or unreasonable step will not lead to the convergence trend. 2 continuous load margin is determined by the trend for a particular network status and specific in terms of load growth. When changing the growth mode or network structure or parameters are changed, the load margin is calculated continuous trend will change. 3 So far, there has been a continuous trend based on load growth, based on network fault and continuous flow and so on.)

1. 了解发电机突然短路的暂态过程； 2. 学会用MATLAB对同步发电机突然短路的暂态过程进行数值计算； 3. 学会用Simulink对同步发电机突然短路的暂态过程进行建模仿真。 (1 understand the transient process of generator short circuit 2 learn to use MATLAB to calculate the transient process of synchronous generator 3 learn to use Simulink to simulate the transient process of synchronous generator.)

使用matlab来比较4种不同的编码的性能。环境是BEC（删除信道）。 信号串的长度为2000(Use matlab to compare the performance of four different codes. Environment is the BEC (binary erasure channel). Length of the signal sequence is 2000)

语音信息处理的好帮手，希望大家支持，非常感谢各位大侠(Voice messaging is a good helper, hope you will support, thank you heroes)

说明：  绘制雷达扫描图，同时能根据从串口传来的参数动态地以黑点显示雷达扫描到的物体，同时能显示摄像头捕捉到的图像(Mapping radar scan at the same time according to the parameters coming from the serial port to dynamically scan radar black spots show the objects, while showing the camera captured images)

说明：  LDPC 预编码，用于构造Raptor码(LDPC Precodes, Used to construct Raptor codes )

用MATLAB实现gold序列的子函数，可在主函数中调用，生成2^n-1长度的gold序列。(use MATLAB to make out gold sequence，which obtained 2^n-1 data.)

The onset of the P wave is the starting point of the P wave, it s the first positive or null sample before the P peak. The offset of the P wave is the ending point of the P wave, it s the first negative or null sample following the P peak.
