Hi everyone,
I am writing to ask a question - how to fit a non-linear curve to another one curve (that follows the same power law) on Matlab. I intended to use least squared fit; however this doesn't seem right because the two curves will be moved to a third position. What I want is to find out the scaling factor for one curve to the other.
Thanks Yunpeng

Huh? Define the model you will assume. If you want a scale factor only in it, then your model is:
f1(x) = a*f2(x)
where a is to be estimated. What about that model will move any curve to a new position?
