trainNetwork error- categorical responses

Hi, I am not able to resolve the problem with my Neural network

I tried my network on example data set: Breast Cancer

inputs: cancerInputs 9x699

targets: cancerTargets 2x699

I change targets in categorical, but there is still the same error:

>> c = categorical(cancerTargets);

>> net = trainNetwork(cancerInputs,c,layers_4,options)

Error using trainNetwork (line 170)

Invalid training data. Responses must be a vector of categorical responses, or a cell array of categorical response sequences.

You can refer to the docoumenatation of trainNetwork.

As per your syntax of trainNetwork: net = trainNetwork(X,Y,layers,options), Y i.e., c in your question should be a N-by-1 categorical vector of labels, where N is the number of observations(=699 in your question). Make sure that the data format of your training data cancerInputs & c is according to the data format mentioned in the docoumenatation of trainNetwork.
