Why is fitnet(10) not working ?

Hi,

I have some troubles using the neural network toolbox for my internship at BASF. I am using a Matlab distribution licensed for BASF - no student license. The neural network toolbox is included. When I use the fitnet function (e.g. fitnet(10)) I receive the following error:

"Undefined function or variable 'network'.

Error in feedforwardnet>create_network (line 101) net = network;

Error in feedforwardnet (line 69) net = create_network(param);

Error in fitnet>create_network (line 98) net = feedforwardnet(param.hiddenSizes,param.trainFcn);

Error in fitnet (line 70) net = create_network(param);"

I already deleted some shadow mse:

">> which -all mse C:\Program Files\MATLAB\R2013b\toolbox\nnet\nnet\nnperformance\mse.m"

The version of the toolbox is recent, so no need to update.

But the problem is still there. Could you help me about that ?

Best regards, Jan

Post your code.

fitnet(10)

is enough of example code for a start. Please check licensing and installation first:

 license('test', 'neural_network_toolbox')

Should return:

ans =
   1

And the result of the "ver" command should have a line like this:

Neural Network Toolbox                                Version 8.2.1      (R2014b)

[Dhandapani.S]

license shows 1.

the ver shows 8.0 R2012b.

but when i type fitnet(10) i get the following error

Error using feval
Undefined function 'initlay' for input arguments of type 'struct'.

Error in nn_configure_bias (line 13)
  net = feval(net.initFcn,'initialize',net,'b',i);

Error in network/subsasgn>setBiasConnect (line 771)
    net = nn_configure_bias(net,i);

Error in network/subsasgn>network_subsasgn (line 59)
    if isempty(err), [net,err]=setBiasConnect(net,biasConnect); end

Error in network/subsasgn (line 13)
net = network_subsasgn(net,subscripts,v,netname);

Error in feedforwardnet>create_network (line 104)
  net.biasConnect = true(Nl,1);

Error in feedforwardnet (line 69)
    net = create_network(param);

Error in fitnet>create_network (line 98)
  net = feedforwardnet(param.hiddenSizes,param.trainFcn);

Error in fitnet (line 70)
    net = create_network(param);

please help

'license ...' returns 'ans = 0'

but 'ver' links to 'Neural Network Toolbox'

[Andreas Goser]

Then it is installed, but not licensed. Can be a couple of reasons. Like a trial, but it was not purchased. Or a larger network license where IT installed all the same on all machines, but some products are only available for one department.

You can send me a PN with your license number and I will help you with that.
