1. Re: Neural Network Toolbox setup

Hi Russel

I'm realy astonished how much problems can occure to install a package.
I have written this package but to pack it for the octave package manager,
I needed a lot of help from David Bateman. I installed the octave-forge version
some times and each time, it worked (almost) perfect. Now I have seen
that someone else changed something at the package. But I think it should
still work!

Try following steps:

start octave, at the command prompt, enter: version
in my case, the answer is "ans = 3.0.0"
now enter: help newff, in my case "help: 'newff' not found" ... this means, no 
nnet package is installed, so now I 
download
the newest nnet-package and save it to "D:/"  (yes, I'have to work on the 
windows version, but maybe I will find time 
todo it 
tomorrow on the ubuntu linux pc)
I change the command prompt on octave to "d:/"
with the command ls, I can see, if the package is in the current working 
directory. If it is, I enter
at the command prompt of octave:
pkg install nnet-0.1.7.tar.gz
after the installation, enter again "help newff" and you should see a short help
and "newff" is used to initialize a new neural network, so the package is 
installed.

I hope this short guide will help

Michael
