使用 SQL 合计函数 你可以确定数据组的各种统计。你可以把这些函数用于查询和合计表达式，条件是在具备 SQL特性的 QueryDef对象中或在创建基于SQL查询的 Recordset对象时-You use the SQL aggregate functions to determine various statistical data sets. You can put these functions together for query and expression, on the condition that the availability of SQL characteristics QueryDef object or create a SQL query based on the Recordset object

L7，elf 程序源代码 可以通过编出其他程序-L7, elf program source code can be compiled out of other programs

通过欧几里德距离对三维空间内的数据点进行聚类： 从文件读入三列表示坐标的数据进行聚类。按项目总数和组数平均划分。首先计算两两之间的距离，选出最近的两个点，再按距离由小到大排序，找出距这两个点最近的若干个点。 除去这些点后对其余的点重复进行上述操作。-By Euclidean distance on three-dimensional space, clustering of data points: from the file read into the three coordinates of the data indicated that cluster. According to the average number of total number of projects and group division. First, calculate the distance between 22 to elect the nearest two points, and then from small to large order to identify these two points away from a number of recent points. After removing these points the rest of the point of repeating to carry out such operations.
