I have experimental data for exponential distribution a*exp(b*x). I need to find coefficients a, b and their errors. I have used function fit(B,C, 'exp1') and I got some results. I have problem because some data points in my file have higher error rate because of the nature of experiment.
1.) Which algorithm or function in Matlab can give the smallest error ? 2.) How can I use/adopt some function in Matlab to put smaller weight (when I calculate coefficients) on data that drastically differ from exponential function ?
