How can I update my newff functions to the updated functions feedforwardnet or patternnet?

I have been using "newff" in a neural network code and it works fine but gives the error message

Warning: NEWFF used in an obsolete way. 

> In obs_use at 17

    In newff>create_network at 126
    In newff at 101

            See help for NEWFF to update calls to the new argument list.

When you go to help, it recommends using feedforwardnet instead.

The program runs fine, but since it is obsolete I figured I should work towards updating it, I'm fairly new at MATLAB and can't quite seem to figure it out. It would be appreciated if anyone could help me out.

% construct an ANN with two hidden layers

net=newff(range,[hn1 hn2 1],{'logsig' 'logsig' 'logsig'}, 'trainlm');

% Set up training parameters
net.TrainParam.epochs=itr;
net.TrainParam.goal=arr;
net.TrainParam.min_grad=0.1*10^(-15);

neural network , newff , patternnet
