ISAR对4个点目标进行仿真成像

simulation of slm papr reduction

function yhat = logistic(bayta,X)

这是2014年在自然杂志上发表的密度峰聚类的代码(This is 2014 in Nature magazine published the density peak clustering code )

通过最小二乘法及SVD-TLS法对同一谱进行了功率谱分析，并比较了不同阶数下，最小二乘法的效果(By least-squares method and SVD-TLS method to the same spectra of the power spectrum analysis, and compare the number of different bands under the effect of least-squares method)

说明：  Radon变换的matlab工具包，大家可以看看(radon&matlab)

实现hmm基本算法。此代码实现基本的viterbi算法。有学习功能(The matlab code implements Viterbi algorith to realize HMM s learning.)

利用采样得到的多组数据，绘制出采样点的三维立体图形。(The use of multiple sets of sampled data, draw samples of the three-dimensional graphics.)

可以用于POD分析，得到不同模态以及重建流场(It can be used for POD analysis to obtain different modes and reconstruct flow field)

直接法，间接法，AR普 功率谱估计,其他的自己看文档就能明白了(Direct method, indirect method, AR & P power spectrum estimation, the other will be able to understand a document that looks at)

本代码为最佳滤波器的研究，关于维纳滤波器的设计实验(This code is the best filter research, design experiments on the Wiener filter)
