function [w1,b1,w2,b2,w3,b3,tr,rq] = lttr3(w1,b1,f1,w2,b2,f2,w3,b3,f3,...					xc,P,T,VA,VAT,TE,TET,TP)%LTTR3 Trains a large feed-forward network with one hidden layer%using a truncated Gauss-Newton method on a Tikhonov regularized problem.%%The general design of LTTR3 is much the same as the design of the %functions in the Neural Network (NN) Toolbox from MathWorks even though the%calling sequences differ. See Neural Network Toolbox User's Guide from the%MathWorks Inc.%%LTTR3 is intended for problems so large that explicit storing of%the corresponding Jacobian matrix is impossible or inconvenient.%For smaller problems where the Jacobian can be stored in main memory, there%is a function TTR3 that uses the Gauss-Newton method (not truncated)%on a Tikhonov regularized problem. However, even for smaller problems LTTR3%is often to be prefered to TTR3 (not to mention the Levenberg-Marquardt%implementations in the NN Toolbox) since it is normally much faster.%%You can find more details in two papers by Eriksson J., Gulliksson M.,%Lindstr鰉 P. and Wedin P-
