Thread Subject: problem with train command function

Hi all,

I tried to use the command function of train. Reading the
Neural Network Toolbox™ 6 User’s Guide, on page 1-26 and
1-27 it refered that after running train function Matlabs
automatically opens neural network training. When i tried
train function I did not get that. Is there any problem or
special adjustment that I have to do?

Thank you in advance,

Manolis

Tou have to create the net with newff or new?? before using
train. if this doesnot solve your problem, please post your
relevant code.

Hope this helps.

Dear Greg,

I load the sample data housing

load housing

I do create the net with

net = newff(p,t,100)

and then I train the net

net = train(net,p,t);
TRAINLM-calcjx, Epoch 0/100, MSE 6579.73/0, Gradient
26421.3/1e-010
TRAINLM-calcjx, Epoch 10/100, MSE 0.0381886/0, Gradient
24.8268/1e-010
TRAINLM, Validation stop.

My version is R7.5.0 (R2007b)

Thank you in advance,

Manolis

It sounds like you're trying to use an older version of the Toolbox with the
documentation for the newest version, Neural Network Toolbox 6.0 (R2008a).
The nntraintool GUI to which I believe you're referring was introduced in
this version of the toolbox, as mentioned in the release notes for this
version.

http://www.mathworks.com/access/helpdesk/help/toolbox/nnet/rn/rn2.html#87460

It is not available in previous versions of the toolbox.
