Curve Fitting

Objective: for linear polynomial clear all close all clc cp_data=load('data'); temperature=cp_data(:,1); cp=cp_data(:,2); [p,S,mu]=polyfit(temperature,cp,2); predicted_cp=polyval(p,temperature,S,mu); ste=sqrt(diag(inv(S.R)*inv(S.R')).*S.normr.^2./S.df); %to get uncertainity or standard deviation of coefficients plot(temperature,cp,'linewidth',2)…
