在MATLAB中聚类连通方(Clustering Connected Squares in MATLAB)

 假设有一个以特定模式着色的网格： 
 
 如您所见，这62个红色正方形在三个不同的组（群集）中连接在一起。 您可能希望从以下链接下载数据。 
 
 点击此处下载网格坐标（XX，YY，ZZ）及其颜色（C） 
 
 然后，您可以使用以下代码生成下面的网格： 
 
load('data.mat');
figure('units','normalized','outerposition',[0 0 1 1]); % Opening big figure
axis equal; axis off;
SURF = surf( XX , YY , ZZ, C);
 
 现在，我正在寻找可以分割这三个集群的代码。 
 
 请记住，您应该将这些正方形视为一组在任何方向上具有最大一平方间隙距离的正方形。 这意味着，在这种特殊情况下，我们有三个11,13和38个方块。 
 
 提前感谢您的时间。 

Assume there is a mesh which is colored in the specific pattern: 
 
As you can see, these 62 red squares are connected together in three different groups(Clusters). You might like to download the data from the following link. 
 
Click here for downloading mesh coordinates (XX, YY, ZZ) and its colours(C)
 
Then, you can generate the mesh below with this code:
 
load('data.mat');
figure('units','normalized','outerposition',[0 0 1 1]); % Opening big figure
axis equal; axis off;
SURF = surf( XX , YY , ZZ, C);
 
Now, I am looking for a code which can segment these three clusters. 
 
Please bear in mind that you should consider those squares as a one group which have maximum one square gap distance in any direction. It means, in this particular case, we have three clusters of 11 , 13 and 38 squares. 
 
Thank you in advance for your time.
