Weights after training

I am trying to train a neural network with Input values and targets. However after training the network I want to be able to view the weights (values) after the training so I will be able to compare them from the initial weights.

How do I do this? I have been using the method net but it does not give me the actual values after training.

Answer 1

[Walter Roberson]

Access net.IW (input weights) and net.LW (layer weights). For more information, see here

Answer 2

you can access the weight using the following code

InputWeight=net.IW LayerWeight=net.LW Bias=net.b

Answer 3

for my case I created the Mfile from the gui. and then modified it to train a network using traingda function(varying learning rate). the function name in mfile is as follows: function net = HHR2(inputs,targets) ...... what should I type on the command window to access the weights? this one doesn't work: net.IW or HHR2(pn,tn).IW (pn and tn are the data included in my folder)

Thanks
