说明：  fft快速傅立叶变换源代码 打包下载 相信对大家有一定帮助(fft Fast Fourier Transform source code package to download that will definitely help all of us)

MATLAB 工程数学应用,许波,刘征编著(The MATLAB engineering mathematics application, Xu Bo, Liu Zheng eds)

老师自己总结的学习Matlab的PPT，一共分为十章，适用于教学和自学等等。(Teacher s own summary of the learning Matlab PPT, the total is divided into ten chapters, suitable for teaching and self-learning.)

说明：  对LFMCW雷达进行发射和接收信号的仿真，并进行测距(Simulation of LFMCW radar transmitting and receiving signals, and ranging)

说明：  一个简单的代码，用于说明OFDM发送器和接收器的操作，包括RF上变频和下变频；(A simple code to illustrate the operation of an OFDM transmitter and Receiver including RF upconversion and down-conversion ;)

matlab二维拟合函数表达式 应用于lsqcurvefit(@myfun,a0,data,zdata) (非线性最小二乘法拟合)(curve fitting)

说明：  基于点的位姿估计，用的是正交迭代算法，国外论文的源代码(Point-based pose estimation, iterative algorithm using the orthogonal)
