I have a neural network license, and am able to execute the first two examples found in the Matlab documentation here: https://ch.mathworks.com/help/nnet/ref/train.html

These use the builtin 'maglev_dataset', which is 1 dimensional. However, the other examples using the 'vinyl_dataset', which has more than 1 dimension, all throw the following error immediately.

>> [x,t] = vinyl_dataset; 
>> net = fitnet([60 30]); 
>> net = train(net,x,t); 
Index exceeds matrix dimensions.
