MATLAB: Problem with defining networks

autoregrissevieneural networknonlinear

Hi all, I found a code online which written by someone and I tried to run it to see how it work in neural networks But it always stops in the same line every time, even with the other codes
 A = 1:1000;  B = 10000*sin(A); C = A.^2  +B;
 Set = [A' B' C'];
 input = Set(:,1:end-1);
 target = Set(:,end);
 inputSeries = tonndata(input(1:700,:),false,false);
 targetSeries = tonndata(target(1:700,:),false,false);
 inputSeriesVal = tonndata(input(701:end,:),false,false);
 targetSeriesVal = tonndata(target(701:end,:),false,false);
 inputDelays = 1:2;
 feedbackDelays = 1:2;
 hiddenLayerSize = 5;
 net = narxnet(inputDelays,feedbackDelays,hiddenLayerSize);
it stop in the last line and the error msg is:
 Undefined function or variable 'network'.
 Error in feedforwardnet>create_network (line 101)
  net = network;
 Error in feedforwardnet (line 69)
    net = create_network(param);
Please help me to understand what is the problem. thank you.

Best Answer

I ran your code with no error messages.
Therefore you need to check version, license and installment.
Hope this helps.
