constrained least square fitting
显示 更早的评论
Hey
I need some help with constrained least squares. I have a vector A(mx1). I need to fit a degree n-polynomial f with a constraint that the f(1)=f(m). I am acquainted with matlab but never done curve fitting and some lead will be great help.
Thanks

How strict does the tolerance have to be on f(1)=f(m) ? If they must be exactly equal, that can be difficult to achieve due to standard round-off error issues.

You can use lsqnonneg or if you have the Optimization TB then Least Squares (Model Fitting) Algorithms
