Simple Neural network binary predictor

How can I change t x and t or simplefir_dataset from the code below to multiple inputs such as:

x = 000 , t = 0

x = 001, t = 0

...

x = 1, 1, 0, t = 1

...

(How can I make my own dataset?)

[x,t] = simplefit_dataset;

net = feedforwardnet(10);

net = train(net,x,t);

view(net)

y = net(x);

perf = perform(net,y,t)
