what is equation of pureline based on neural network toolbox? as i have read before, that purelin transfer function is a = purelin(n) = n. but from simulation in neural network toolbox get different result from the equation. is the equation wrong?
thank you.

How are we supposed to know what you did wrong if you don't demonstrate it???

so, we must set input range -1 to 1 sir?
with normalization?
because, based example that i have tried, the target that i want is 0 or 1, but in equation, i got the result many variation, like 2, 3, even 23491.
i don't know what's wrong.
