Nice, which course do you take part in, maybe some other course participants
can help you out here or benefit from other answers.

Most of us have a great idea about standard Octave stuff, but are not
necessarily experts on neural networks, or on the code you are trying to run
;-)

This is good news.

And I am puzzled of the huge and still incomplete example you provided (what
are all the sub-functions doing, i/o maybe?).  Consider to use a MCVE
<https://stackoverflow.com/help/mcve> if you are honestly looking for help. 
Maybe attach long files to your email to not get wrapped, or better upload
all of the required code to some public service, attaching a link to it. 
Like NJank said, it is more guessing than answering what we can do for you
at the moment.

HTH,
