本文件为本人学习matlab编成期间的部分笔记内容，都是比较重要的知识点和初学者十分容易出错或者十分困惑的问题。包括函数的重要概念，GUI回调语句中的引号问题，点运算等等。()

说明：  QPSK详细调制解调的源码，包括整个流程．(QPSK modulation and demodulation of the source in detail, including the entire process.)

将一个整数转换成二维数组，数组每行的次序依次为1,2,3……(Convert an integer into two-dimensional array of each line in the order followed by 1,2,3 ......)

惯性导航程序，matlab编辑，旋转矢量法结合方向余弦矩阵，完美计算姿态阵，惯导姿态更新程序(Inertial navigation procedures, matlab editing, rotation vector direction cosine matrix method combined with perfect posture matrix calculation, INS attitude update)

QPSK调制与解调，低通滤波器采用了时域和频域两种实现方式，截止频率fc = 200hz,采样频率fs= 1000hz,欢迎下载参考！(QPSK modulation and demodulation, using a low-pass filter with a time domain and frequency domain implemented way, the cutoff frequency fc = 200hz, the sampling frequency fs = 1000hz.Welcome to download !)

CoMP 技术是LTE-A 的关键技术之一，能 够显著的提高小区吞吐量和边缘用户速率。文章 首先阐述了CoMP 的技术优势；随后介绍了 CoMP 的技术原理，系统模型以及传输方案等方 面的内容；最后总结CoMP 技术面临的机遇和挑 战。(CoMP technology is one of the key technologies for LTE-A, can significantly increase the rate of cell throughput and edge user. This paper described the technical advantages of CoMP subsequently introduced of CoMP technology principle, the system model and transmission scheme aspects concluded the opportunities and challenges faced by the CoMP technology.)

基于深度优先搜索的电力系统分区：根据节点连接关系确定节点的所属分区，即系统最终分成多少个区域、每个区域包含哪些节点。(Power system Partition based on deep search according to connectivity , i.e., determining the number of sections and nodes in each section.)
