BEST FIT OF SCATTERED DATA

1 ビュー (過去 30 日間)
Hello Beautiful,
I came up with the attached plot of scattered data, and because I'm not so good at fitting techiniques, and less in Matlab,
I wonder if someone can give me some tips on how to best fit the data.
Thanks in advance to everyone, and take care.

Let (x,y) be your points.
p = polyfit(x,y,1) ; % change the degree
yi = polyval(p,x) ;
plot(x,y,'.r',x,yi,'b')

Dear KSSV,
thanks for your help.
It was useful, and I used polynomials as fitting functions.
I wonder if novel methods exist to divided data in clusters, and then used and combined different fitting functions along the data pattern distribution.
Best.
