I keep getting the error "Index exceeds array bounds".

% INITIALIZE THE NEURAL NETWORK PROBLEM %

% inputs for the neural net(AND gate example== 2 inputs && 4 samples)
inputs = inputs';

% targets for the neural net
targets = TargetNormalized';

% number of neurons
n = 4;

% create a neural network
net = feedforwardnet(n);

% configure the neural network for this dataset
net = configure(net, inputs, targets);

% get the normal NN weights and bias
getwb(net)

% error MSE normal NN
error = targets - net(inputs);

% PLEASE NOTE: For a feed-forward network
