Hallo! I have a code:
nndata=[nndata;testdata1];
nnlabels=[traininglabels; testinglabels];
inputs = nndata';
targets = nnlabels';
hiddenLayerSize = 25;
netx = patternnet(hiddenLayerSize);
netx.divideParam.trainRatio = 70/100;
netx.divideParam.valRatio = 15/100;
netx.divideParam.testRatio = 15/100;
netx.trainFcn='trainlm';
[netx,tr]=train(netx,inputs,targets);
I am getting the error as:
??? Undefined function or method 'eq' for input arguments of type 'network'.
Error in ==> C:\Programmi\MATLAB\R2011a\toolbox\prtools\@dataset\subsref.p>subsref at 23
Error in ==> automa at 169 net=train(netx,inputs,targets);
This code, with a different computer, runs with no errors. Can someone help me understand what may be the cause? can anyone help me find a solution? Thank you in advance.

That could happen if for some reason it thought "train" was the name of a matrix, such as if the NN code was not installed (or the installation was corrupt.)
Try
which -all train
to see what that system thinks "train" is.

thanks Walter.
MATLAB's response is:
which -all train
train is a variable.
C:\Programmi\MATLAB\R2011a\toolbox\nnet\nnet\@network\train.m % Shadowed network method
I think you're right...
