[Scilab-users] Vector from tlist?

[Stefan Du Rietz]

Thank you Serge, but list2vec uses a loop.

In my simple case, this is perhaps better:

// get an ordinary list by removing the first element:
handles_list = handles_tlist;
handles_list(1) = null();
handles_vec = [];
// put one handle at a time in the vector
for h = handles_list
   handles_vec = [handles_vec; h];
end
// If I want to delete all handles in the list, I can then do:
delete(handles_vec)

But if I anyhow have to use a loop (and don't need the list any more), 
I can do it like this (where handles_list is the tlist):

handles_list(1) = null();
for h = handles_list
   delete(h)
end

Which solution is faster?

Stefan
