Problem creating network fitnet

Hello,

i just wanted to start some pattern recognition using the DeepLearning Toolbox.

When i try to create a simple network, following the tutorial, i just get an error message.

This is my code:

[x,t] = simplefit_dataset;
net = fitnet(10);

Using these lines, i get the following error messages:

Not enough input arguments.

Error in minmax (line 3)
ymax = max(y);

Error in initnw>configure_layer_weight (line 117)
  config.range = minmax(x);

Error in initnw (line 58)
              out1 = configure_layer_weight(in2,in4,in5,in6);

Error in initlay>configure_layer_weight (line 126)
    settings = feval(initFcn,'configure',net,'LW',i,j,x);

Error in initlay (line 55)
              out1 = configure_layer_weight(in2,in4,in5,in6);

Error in nnet.internal.configure.layerWeight (line 26)
    feval(net.initFcn,'configure',net,'LW',i,j,x);

Error in nnet.internal.configure.layer>iConfigurePreceedingLayerWeights (line 74)
    net = nnet.internal.configure.layerWeight(net,i,j,inputRange);

Error in nnet.internal.configure.layer (line 25)
  net = iConfigurePreceedingLayerWeights(net,i);

Error in network/subsasgn>setLayerInitFcn (line 1138)
net = nnet.internal.configure.layer(net,i,net.layers{i}.dimensions);

Error in network/subsasgn>network_subsasgn (line 192)
                            if isempty(err), [net,err] = setLayerInitFcn(net,i,initFcn); end

Error in network/subsasgn (line 14)
net = network_subsasgn(net,subscripts,v,netname);

Error in feedforwardnet>create_network (line 123)
    net.layers{i}.initFcn = 'initnw';

Error in feedforwardnet (line 73)
    net = create_network(param);

Error in fitnet>create_network (line 102)
  net = feedforwardnet(param.hiddenSizes,param.trainFcn);

Error in fitnet (line 74)
    net = create_network(param);
    

I already tried to reinstall the DeepLearning Toolbox, but it did not help.

Checking the licences, i get:

>> license('inuse')
distrib_computing_toolbox
matlab
neural_network_toolbox
statistics_toolbox

Can anyone help me? Thank you!
