std::out_of_range Error

[Na]

Hi all!

I have this error on my code

-->   terminate called after throwing an instance of 'std::out_of_range'
  what():  vector::_M_range_check

Because i cant debug i dont know where is the problem but i think something with the on-off application is going wrong!

Can someone help me?I have the latest lena.

I attach my script.

I forgot to write that the error appears when i set the number of ues above 20-30.
