net = newff(minmax(alphabet),[S1 10 S2],{'logsig' 'logsig' 'logsig' },'traingdx');
net.LW{2,1} = net.LW{2,1}*0.01;
net.b{2} = net.b{2}*0.01;
net.performFcn = 'mse';
net.trainParam.show = 20;
net.trainParam.epochs = 2000;
net.trainParam.mc = 0.95;
P = alphabet;
T = targets;
[net,tr] = train(net,P,T);

This script is defining a feedforward neural network and initializing the weights and network properties itself. newff is obsolete since R2010b release, You can use feedforwardnet in newer release for same functionality.
