MATLAB: Best suitable way for ANN.

artificial neural networkMATLABsolution

Greetings everyone,
I am working on a model of a river system, where by I have 6 years data at 23 sites for 5 parameters. I intend to train the network with initital 5 years data, predict the 6th years data with the trained network and finally compare the predicted values with the actual values.
I searched on the documentation for Machine learning and Neural networks but couldn't find the solution.
