help me ? How many layers?

How many layers are hidden and output ? Is it Backpropagation network ?

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);

1. ONE HIDDEN LAYER IS ALWAYS SUFFICIENT! 2. NEWFF is obsolete, Do you have FITNET?

 help fitnet

 doc fitnet

2. If you are really serious about getting help, use the example data in

 help newff      %or help fitnet

and

 doc newff       %or doc fitnet

Additional data can be obtained from

 help nndatasets

and

 doc nndatasets
