Hi, I have some problem regarding the polynomial curve fitting. I compute coefficient from Data A using fifth degree polynomial and the sample coefficient obtained from Data A was used back to Data B (to reconstruct similar to Data A). My question is did the polynomial considered my Data B also to fit the curve ?

No it will not consider data B. It gives polynomial coefficients based on Data A. If your data B x ranges are same as data A x ranges, then data B can be fitted with this polynomial.

x = linspace(0, 4*2*pi, 501);
x(end) = []; %4 cycles would not touch 0 a fifth time
S4 = sin(x);
