调整网格颜色:调整 x、y 和/或 z 网格颜色-matlab开发
这段代码定义了一个名为zgrid()的函数,该函数的功能是对数据进行网格化处理并进行聚类。具体实现步骤如下:
1. 调用prepare()函数进行数据准备,包括读取数据、对数据进行预处理等;
2. 调用makegrid()函数对数据进行网格化处理;
3. 调用getCellCount()函数获取每个网格内数据点的数量;
4. 调用caculateAllDensitys()函数计算每个网格内的密度;
5. 调用getThreshold()函数计算阈值;
6. 遍历每个网格,根据其虚拟密度和阈值来确定其所属的簇;
7. 调用removeSmallCluster()函数删除小簇;
8. 调用makeCluster()函数对簇进行合并;
9. 调用maintainCluster()函数对簇进行维护和排序;
10. 最后,绘制聚类结果的矩形图并返回。
该函数的主要作用是对数据进行聚类分析,并将聚类结果可视化。
