cgal_dt2_delete - Delete a pointer that represent dt2.
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.
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.
