Curve fitting a power function
显示 更早的评论
I am wondering how to fit my data to a power function of the form Q=c(h+a)^b
where Q is the flow rate data and h is the stage height. How can I identify a,b, and c?
Thanks,

If h and Q are vectors then try
ft = fittype('c*(h+a)^b', 'independent', 'h');
fit_model = fit(h(:), Q(:), ft);
