ksvd字典学习算法和改进的ksvd字典学习算法，并自动计算psnr。(ksvd dictionary learning algorithm and improved ksvd dictionary learning algorithm and automatically calculates psnr.)

常用函数速查，对matlab开发的人非常有用。(Commonly used functions Info on matlab developed a very useful people.)

k近邻选取，在降维的时候需要构造邻接矩阵，需要选取近邻的个数(k neighborhood selection)

第2种方法SAR雷达在斜视角etha下，雷达回波信号仿真 (SAR ECHO SIMULATION)

本程序是用于信号频谱分析的实验程序。 主要功能是进行信号的幅值谱计算；同时可完成在选定范围内谱峰的精确计算。( This procedure is used to test the program signal spectrum analysis. Main function is to calculate the signal amplitude spectrum the same can be done accurately calculate the spectral peaks within the selected range.)

AFD与AFDPF盲区对应的MATLAB程序.(the NDZ of AFD and AFDPF detection method corresponding MATLAB program.)

说明：  计算hurst指数中几个参数的选择,参数的选择对于这个计很重要,本代码试图找出一个最优的选择.(Hurst index calculation the choice of several parameters, the parameters of choice for this very important, the code to try to find an optimal choice.)
