Training a neural network

I am new to the neural network using Matlab. I have training data with 684 inputs with each consisting of 360 samples whereas, the 684 output labels are of size 6.

I am trying to train a neural network with two hidden layers each consisting 20 neurons, but it is giving me an error. Can you please help me with this?

x=reshape(input,1,[]);
y=reshape(output,1,[]);
net=newcf([0 0.2],[[684,360], 20,20, [684,6]]);
net.trainparam.epochs = 20;
net.trainparam.goal = exp(1)^-25;
net.trainparam.lr = 0.01;
net = train(net,x, y)
