Please help me to understand the code.

This is a code for training Neural Network:

function [net]=createff(Iin,Target)

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);

net = train(net, Iin, Target);

end

Please help me to understand this code.
