虚拟阵列扩展的MUSIC算法,采用前后向平移(virtual array extension MUSIC)

Finite impulse response filter

关于matlab的一本不错的基础教程，对于初学者是一个不错的选择，当然对于长时间从事这方面的人来讲，也是一本不错的查询资料(On the basis of a good matlab tutorial for beginners is a right choice, of course, for long time engaged in this aspect, it is also a good inquires the material)

有CDF三角函数曲线/三维曲线图，插值与拟合的matlab实现，部分实现了追踪测速迭代松弛算法。( There CDF trigonometric curve/3D graphs, Interpolation and fitting matlab implementation, Partially achieved tracking speed iterative relaxation algorithm.)

用GPS和惯性导航做组合导航，组合导航采用的滤波器为卡尔曼滤波器。(GPS and inertial navigation are used to make integrated navigation. The filter used in integrated navigation is Kalman filter.)

基于神经网络的matlab模型，解决ＳＩＲ模型问题。(Matlab code for SIR model, based on BP)

对模拟信号抽样，然后进行离散傅里叶变换，利用自编DFT函数，得到频谱，然后进行频谱的还原。(Sampling the analog signal, then the discrete Fourier transform, DFT self function obtained spectrum and the spectrum reduction.)

prony工具箱用于对信号进行prony分析，(We have designed a software tool in MATLAB, the Prony Toolbox, to perform Prony analysis. Prony Toolbox (PTbox) is designed based on several considerations including data preprocessing, model order selection, model order selection criteria, signal subspace selection, signal and noise separation, root inspection and assessing residuals. The PTbox provides flexibility to compare and display analysis results simultaneously for several parameter variations.)

Gabor特征计算：平均能量和平均幅值[gaborSquareEnergy, gaborMeanAmplitude ]= phasesym(im) (Computation of Gabor Features- Mean Squared Energy, Mean Amplitude >>> im = rgb2gray(imread( 001.png )) >>> [gaborSquareEnergy, gaborMeanAmplitude ]= phasesym(im) )
