Error when running patternnet example code from Help documentation

I am attempting to run the example code from the Help documentation for function patternnet:

[x,t] = iris_dataset;
net = patternnet(10);
net = train(net,x,t);
view(net)
y = net(x);
perf = perform(net,t,y);
classes = vec2ind(y);

I get an error in the command window when when I try to run patternnet(10):

Error using boiler_transfer (line 98)
Unrecognized code: 'defaultParam'

Error in softmax (line 75)
boiler_transfer

Error in network/subsasgn>getDefaultParam (line 2048)
    param = struct(feval(fcn,'defaultParam'));

Error in network/subsasgn>setLayerTransferFcn (line 1224)
net.layers{i}.transferParam = getDefaultParam(transferFcn);

Error in network/subsasgn>network_subsasgn (line 208)
        if isempty(err), [net,err] = setLayerTransferFcn(net,i,transferFcn); end

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

Error in patternnet>create_network (line 104)
  net.layers{net.numLayers}.transferFcn = 'softmax';

Error in patternnet (line 71)
    net = create_network(param);

Can anyone shed some light on what is going wrong? I am running Matlab 2014a.

Regards

Bob

From the error, it looks like you could have another function softmax that shadows the one shipped with the product. So you might want to try the which command:

which -all softmax

If this lists more than the softmax at the location 'toolbox\nnet\nnet\nntransfer\softmax.m', you might want to remove the other softmax.m from your path before using the patternnet function.

This was the issue - I'd installed a 3rd party toolbox which meant I had another copy of softmax in the path. Thank you for your help.

[Jason Potas]

Awesome thanks, that was also my issue; a deep learning toolbox also had a softmax function in a different path, so by removing it from the set paths it now works fine.

It works.Thank you very much 6_0

The only thing that I can think of is to use clear or clear all before using those 7 commands.
