matlab实现快速傅立叶变换，采用了矩阵法(matlab realize fast Fourier transform using the matrix method)

This program do the NMF based clustering

非线性回归通用程序,稍加修改即可用于各种非线性回归(General non-linear regression procedures, a little modification can be used for various non-linear regression)

ITU标准下的大气传播衰减计算程序，使用简单方便，只需要输入传播角度，高度，气候环境，即可计算大气传输损耗（不包括自由空间传播损耗）(According to the ITU standard, this program calculates the atmospheric loss. It is simple to use, you only have to input some parameters such as height, elevation angle, etc)

This folder has two files for the simulation of universal motor. please run the *.m file to run the *.mdl file(This folder has two files for the simulation of universal motor. please run the*.m file to run the*.mdl file)

功率谱密度函数，AR谱估计方法，Burg递推算法(The power spectral density function, the AR spectral estimation method, the Burg recursive algorithm)

说明：  简化了整个程序流程，在三维隐函数作图方面有较大的应用(It simplifies the whole program flow and has great application in drawing three-dimensional implicit function.)
