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.

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.
