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.

1. delete the net = init statement because newff is self-initializing.
2. Before using a code specifying various parameter values that overwrite default values, it is probably worth your while to try using as many defaults as possible. See the examples in
help newff
doc newff

The first line creates a feed-forward backpropagation network. Type this in the command window to learn more:
help newff
The last two lines initialize and train the network.
help init
help train
