what is the purpose of the last line?

net = newff(Iin, Target, 10, {'logsig' 'logsig'}, 'trainscg');

net.trainParam.perf = 'sse';

net.trainParam.epochs = 500;

net.trainParam.goal = 1e-5;

net.trainParam.lr=0.15;

net.trainParam.mc=0.8;

net = init(net);

I know init is used for initializing a ts-collection object with new time or new time series. So, is it used in the last line to collect the objects of all net.trainparam lines? I don’t understand it. Please help me.

init initializes a net with random weights.

However, the command is totally unnecessary because newff is self-initializing.

So: Delete it and don't worry about it.

However, I am concerned about why you are not using MATLAB defaults for your design. Try

 net = newff(Iin,Target) % NO SEMICOLON

Then see the defaults that MATLAB gives you free of charge.

Compare with the ones you have chosen

Also try the code in

help newff

Hope this helps.
