Complex value computed by model function, fitting cannot continue. Try using or tightening upper and lower bounds on coefficients.
Hello, I really need some help on data fitting. I would like to fit my data custom equation:a+b*exp((-(x/c))^d. I try to use upper and lower bounds on coefficients but it does not work.If anyone can tell me what to do to resolve this I would greatly appreciate it.Hello, I really need some help on data fitting.
