cgal_dt2_delete - Delete a pointer that represent dt2.

Calling Sequence

cgal_dt2_delete(ptr,"ptr")
cgal_dt2_delete()

Parameters

Description

Given a pointer ptr of dt2, cgal_dt2_delete(ptr,"ptr") frees the memory holded by the pointer ptr and clears ptr in Scialb interpreter. if no parameters are given to cgal_dt2_delete(), then all pointers of differents dt2 will be deleted.

Examples



x = rand(1,10);
y = rand(1,10);
new_x = rand(1,10);
new_y = rand(1,10);
//example 1:

[tri,ptr] = cgal_delaunay_2(x,y);
cgal_dt2_insert_points(ptr,new_x,new_y);
new_tri = cgal_dt2_get_connectivity(ptr);
cgal_dt2_delete(ptr,"ptr"); // ptr is deleted here and cleared from scilab interpreter.
ptr
  !--error     4
undefined variable : ptr
//example 2:
[tri1,ptr1] = cgal_delaunay_2(rand(1,10),rand(1,10));
clear ptr1; // ptr is not yet defined in scilab interpreter, but the memory is not freed.
cgal_dt2_delete(); // all pointers of dt2 will be deleted.
