doc/neuralnetworktutorial.md Loading the saved Experiment - needs extra line: require 'optim'

on starting a new session with 'th' and entering:
require 'dp'
xp = torch.load("/home/george/save/d2:1456235877:1.dat")
I get:
/home/george/torch/install/share/lua/5.1/torch/File.lua:334: unknown Torch class <optim.ConfusionMatrix>
stack traceback:

if instead I do:
require 'dp'
require 'optim'
xp = torch.load("/home/george/save/d2:1456235877:1.dat")
then it runs ok.

Am I right to say that you should add the extra line:
require 'optim' to your example?

(I'm just starting to use Torch, and I am having problems reloading other nnet examples as well, but this seemed the simplest example (and the only one I have got to work) so I thought I would ask about it first)

Thankyou,
George

@george-colin Yes you are right. I just update the doc. Thank you.
