NewK-means-clustering-algorithm
说明： 珍藏版，可实现，新K均值聚类算法，分为如下几个步骤：
一、初始化聚类中心
1、根据具体问题，凭经验从样本集中选出C个比较合适的样本作为初始聚类中心。
2、用前C个样本作为初始聚类中心。
3、将全部样本随机地分成C类，计算每类的样本均值，将样本均值作为初始聚类中心。
二、初始聚类
1、按就近原则将样本归入各聚类中心所代表的类中。
2、取一样本，将其归入与其最近的聚类中心的那一类中，重新计算样本均值，更新聚类中心。然后取下一样本，重复操作，直至所有样本归入相应类中。
三、判断聚类是否合理
采用误差平方和准则函数判断聚类是否合理，不合理则修改分类。循环进行判断、修改直至达到算法终止条件。(NewK-means clustering algorithm ，Divided into the following several steps:
A, initialize clustering center
1, according to the specific problems, from samples with experience selected C a more appropriate focus the sample as the initial clustering center.
2, with former C a sample as the initial clustering center.
3, will all samples randomly divided into C, calculate the sample mean, each the sample mean as the initial clustering center.
Second, initial clustering
1, according to the sample into the nearest principle clustering center represents the class.
2, as this, take the its recent as clustering center of that category, recount the sample mean, update clustering center. And then taking off, as this, repeated operation until all samples into the corresponding class.
Three, judge clustering is reasonable
Adopt error squares principles function cluster analysis.after clustering whether reasonable, no reasonable criterion revisio)

regular_mesh
Finland
Matlab cannot do regular meshes for non-regtancular regions.
However, one can manually do very coarse regular meshes for
these type domains. The difficulty is with the edge data e.
If this data does not correspond to the orientations given by
the PDEtool geometry files, refinement will not work. The
function drawedges() will display the order of the edges and
their segment numbers. However, this function does not tell
how the edges are oriented. However, just run the visualization,
and if the refinement does not work correctly, you know the
problem is with the orientatino of the edge. Remember to also
correct the last two rows of the matrix e when changing the
orientation. (See the documentation for initmesh for more info.)

matlab_ipt_tutorial
The purpose of this tutorial is to gain familiarity with MATLAB’s Image Processing
Toolbox. This tutorial does not contain all of the functions available in MATLAB. It is
very useful to go to HelpMATLAB Help in the MATLAB window if you have any
questions not answered by this tutorial. Many of the examples in this tutorial are
modified versions of MATLAB’s help examples. The help tool is especially useful in
image processing applications, since there are numerous filter examples.
