csgdel

Delete borders between minimal regions

Syntax

-     [dl1,bt1]=csgdel(dl,bt,bl)
      [dl1,bt1]=csgdel(dl,bt)

Description

`[dl1,bt1]=csgdel(dl,bt,bl)` deletes the border segments in the list `bl`. If the consistency of the Decomposed Geometry matrix is not preserved by deleting the elements in the list `bl`, additional border segments are deleted. Boundary segments cannot be deleted.

For an explanation of the concepts or border segments, boundary segments, and minimal regions, see `decsg`.

`dl` and `dl1` are Decomposed Geometry matrices. For a description of the Decomposed Geometry matrix, see `decsg`. The format of the Boolean tables `bt` and `bt1` is also described in the entry on `decsg`.

`[dl1,bt1]=csgdel(dl,bt)` deletes all border segments.
