说明：  此为对于均匀阵列的MUSIC算法的源代码，希望对大家有用(this a uniform array for the MUSIC algorithm source code, we want to help!)

该文件是模拟电磁波传播过程中遇到障碍物遮挡使信号与接收装置之间不能直视而产生的传输误差，对模拟电磁波传播具有很大帮助。(The file is a simulation of the transmission error caused by the obstacle occlusion in the process of electromagnetic wave propagation, which can not be seen directly between the signal and the receiving device. It is of great help to the simulation of electromagnetic wave propagation.)

四轴飞行器制作总结，包括四轴制作过程中马达、电调的选择，以及相关代码。(Four aircraft production summary, including the motor axis in the production process, the choice of power transfer, and the relevant code.)

pwm整流器的建模仿真，一些自适应信号处理的算法，包含位置式PID算法、积分分离式PID，使用matlab实现智能预测控制算法，实现串口的数据采集，双向PCS控制仿真。( Modeling and simulation pwm rectifier Some adaptive signal processing algorithms, It contains positional PID algorithm, integral separate PID, Use matlab intelligent predictive control algorithm, Achieve serial data acquisition, Two-way PCS control simulation.)

这个程序就是从联合开发网下载的，但是有一个错误导致识别率不足60%。 原始版本在图像旋转后提取的指纹中心点算法有误，每次提取的中心点都在图像边缘，造成后面提取的FingerCode也会出错。 这个修改使旋转前的中心点与旋转后的中心点保持一致，同时减少了运算复杂度(This program is downloaded from www.pudn.com, but one error led to recognition rate of less than 60%. The original version of the extracted fingerprint center point after the image rotation is incorrect, and each extracted center point is at the edge of the image, resulting in the wrong FingerCode extracted later. This modification keeps the center point before rotation consistent with the center point after rotation while reducing the computational complexity.)
