Delete borders between minimal regions
[dl1,bt1] = csgdel(dl,bt,bl)
[dl1,bt1] = csgdel(dl,bt)
[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.
