Hi,
I am trying to optimize my ublas-containing code.  The profile from 
gprof showed these two functions as the top 2 time-consuming ones.  
Could somebody explain to me a little bit about what these mean?

  %   cumulative   self              self     total           
 time   seconds   seconds    calls  ms/call  ms/call  name    

 23.76     93.11    93.11 137604968     0.00     0.00  vector<int, 
allocator<int> > * __uninitialized_copy_aux<vector<int, 
allocator<int> > *, vector<int, allocator<int> > *>(vector<int, 
allocator<int> > *, vector<int, allocator<int> > *, vector<int, 
allocator<int> > *, __false_type)

 21.49    177.31    84.20 41208000     0.00     0.00  vector<int, 
allocator<int> >::operator=(vector<int, allocator<int> > const &)

Thanks,

Julian
