I am trying to fitting the data
I want to fitting the data 1 by least square fitting it to a quadratic function around the position of maximum data2(*)
f(x) = a(x-x0)^2 + b(x-x0) + c
where C is an additive constant C = f(x0) = 1.
I used several method (ex data fitting tool...) but failed
If you konw how to solve, pleast let me know
