calculating the error in parameters for exponential fit

Hi all!

Im trying to find the exponential function that discribe my data

(I was using f = fit(x,y,'exp1') ) and i was wondering how can I find the parameter's error (as I can find for the poli fit by (max-min)/3.92)

thanks!

thank you for your answer. i have this information but i want to calculate the absoulot error.

do you know what will be the right equation?
