If you you normalize your inputs and targets using maxmin or mapstd, the function for the normalized variables is
yn = B2 + LW*tansig(IW*xn+B1);
Hope this helps.

clear all, clc
[x,t] = simplefit_dataset;
net = fitnet;
rng(0)
net = train(net,x,t);
IW = net.IW{1,1}
b1 = net.b{1}
LW = net.LW{2,1}
b2 = net.b{2}
whos IW b1 LW b2
Hope this helps.

thanks so if I want to write a function for this how can write this?? here I think we have one feature but w and b are 10, so how can Relating them to each other and make a function for it ?? Suppose that my feature is X.
