i need to develop matlab code for functional page link ann to make a sensor linearisation.

i need a basic matlab code for functional nueral network with four inputs. each input node has 300 records.

Artificial Neural Network Prediction Code in Matlab, please help !!!

Dear ! I have a data set with a column is rainfall and the next column is water level (1992-2006) as: https://docs.googlefile/d/0By5tEg03EXCpd...RzMHM/edit I would like to ask your about what are the Inputs values and Target Values? My friend told me that to Predict water level in the future is not need Rainfall data but only need Water level for recent years ago. I am confusing about that since Neural Network is needing an Input and Target values. I have a code for predict water level but rely on the input data has known, within 1992-2006 only. What I am need is using data from 1992-2006 to predict in the year 2014 example. I know you are very excellent about that, please fix again help me the code, thanks.

% Prepare the Data for Training and Simulation
% The function PREPARETS prepares timeseries data for a particular network,

% Using PREPARETS allows you to keep your original time series data unchanged, while
% easily customizing it for networks with differing numbers of delays, with
% open loop or closed loop feedback modes.

% Early Prediction Network
% For some applications it helps to get the prediction a timestep early.
% The original network returns predicted y(t+1) at the same time it is given y(t+1).
% For some applications such as decision making, it would help to have predicted
% y(t+1) once y(t) is available, but before the actual y(t+1) occurs.
% The network can be made to return its output a timestep early by removing one delay
% so that its minimal tap delay is now 0 instead of 1. The new network returns the
% same outputs as the original network, but outputs are shifted left one timestep.
