The developers of the Neural Network Toolbox™ software have written a textbook, Neural Network Design (Hagan, Demuth, and Beale, ISBN 0-9717321-0-8). The book presents the theory of neural networks, discusses their design and application, and makes considerable use of the MATLAB® environment and Neural Network Toolbox software. Example programs from the book are used in various sections of this documentation. (You can find all the book example programs in the Neural Network Toolbox software by typing nnd.)
