DCT2DPCA

the simulation provides computation of target reflectivity data in the deficient elevation domain. Simulations are implemented to test the decoupled least-squares technique for high resolutionspectral estimation of target reflectivity.all seven (7)files should be downloaded for the simulation to work.(dls3D.m,estimate.m,get2S1Data.m,getConstraints.m, getImageData.m,getPixelData.m, getSLICYData.m)

fast bilateral filter for image denoising

安卓应用，与硬件搭配，可以通过程序控制硬件设备，直接在matlab上实现(Android applications, and hardware mix, can be programmed to control hardware devices, realized directly on matlab)

说明：  有限单元法及其应用 彭细荣，matlab在有限单元中的应用及其代码，可以应用其掌握该方法的弹性求解过程。 (matlab application finite element method )

本书使用MATLAB的基本语法莱实现算法，避免将所要实现的功能隐藏在函数之下，而让读者不知道是如何实现的。非常适合在校学习通信专业的本科生、研究生作为辅导资料。(This book to use MATLAB)

K最邻近密度估计技术是一种分类方法，不是聚类方法。 不是最优方法，实践中比较流行。 通俗但不一定易懂的规则是： 1.计算待分类数据和不同类中每一个数据的距离（欧氏或马氏）。 2.选出最小的前K数据个距离，这里用到选择排序法。 3.对比这前K个距离，找出K个数据中包含最多的是那个类的数据，即为待分类数据所在的类。(K nearest neighbor density estimation is a classification method, not a clustering method. It is not the best method, but it is popular in practice. Popular but not necessarily understandable rule is: 1. calculate the distance between the data to be classified and the data in each other (Euclidean or Markov). 2. select the minimum distance from the previous K data, where the choice sorting method is used. 3. compare the previous K distances to find out which K data contains the most data of that class, that is, the class to which the data to be classified is located.)
