Neural Network Coding Error

Can you please tell me how to give three inputs in newff to generate a block using gensim having three input ports?

My code is:

net10 = newff(p,t,[5 2],{'tansig' 'purelin'})

p=[6.697 6.4 6.281 6.217 6.177 6.150 6.130 6.101 5.121; 6.608 6.307 6.179 6.102 6.405 6.150 6.130 6.101 5.121;

6.604 6.303 6.175 6.098 6.040 5.987 5.929 5.715 4.519]

t=[ 10 20 30 40 50 70 80 90 100]

net10.trainParam.epochs = 200;

net10.trainParam.goal=0;

net10 = train(net10,p,t);

Y = sim(net10,p);

e=t-Y;

plot(p,t,p,Y,'o')

gensim(net10)
