解释1:
The Sets-Tree-Flip Matrix option can be very useful when we have a grid of points divided in an equal set of branches and items on each branch. For example there are 10 branches {0;0;0} etc and on each branch there are 10 data items (n10). A polyline through each 10 items of each branch will generate 10 polylines. However when we flip the matrix a plyline is generated between each first item on each branch and then the second on each branch resulting in a set of crosswise angled lines with the first set.

当我们有一个点的网格划分为一组相等的分支和每个分支上的项目时,Sets-Tree-Flip Matrix选项可能非常有用。例如,有10个分支{0; 0; 0}等,并且在每个分支上有10个数据项(n10)。每条分支的10个项目的折线将生成10个折线。然而,当我们翻转矩阵时,在每个分支上的每个第一项之间产生一条线,然后在每个分支上产生第二个,导致与第一组交叉成角度的线的集合。
