基于MATLAB的matrix_gain详解，主要解决的是matrix_gain的问题(Based on MATLAB-matrix_gain explain, the main problem lies in the question of matrix_gain)

应用傅里叶变换DFT，分析各种离散信号x(k)的频谱。离散周期信号可以展开成傅里叶级数，所以离散周期信号的频谱 是一个周期的周期性离散频谱，各谱线之间的间隔为 ，而且存在着谐波的关系。 (DFT application of the Fourier transform, analyze discrete signal x (k) of the spectrum. Discrete signal cycle can begin as Fourier series, the discrete signal spectrum is a cyclical cycle of discrete spectrum, the line between the interval, but there is a harmonic relationship.)

neural network matlab example

I am doing research in wireless sensor network in data aggregation. here cluster head send packet to base station .by using k means cluster algorthim A network is divided into k layer. k cluster are formed in k layer . each cluster has one cluster head . all cluster member send data to its corresponding cluster head by using TDMA . the cluster head performs the data aggregation and forward packet to base station .

利用matlab进行时域分析，本实验首录了三个音频。并编写程序求其特征值。特征值有平均值，整流平均值方差，标准差，方差，峭度，均方根，波形因子，峭度因子，峰值因子，脉冲因子，裕度因子。还有就是对音频进行自相关分析得出其波形图。(Use matlab time-domain analysis, the first experiment recorded three audio. Programming and seeking the eigenvalues. Characteristic values are averaged rectified mean variance, standard deviation, variance, kurtosis, RMS, crest factor, kurtosis factor, crest factor, pulse factor, margin factor. There is an audio self-correlation analysis of its waveform.)
