curve fitting

Objective: clear all close all clc %to load required data cp_data=load(\'data (1)\'); temperature=cp_data(:,1); cp=cp_data(:,2); %curvefit %cp=a*t^2+b*t+c co_effs=polyfit(temperature,cp,1); predicted_cp=polyval(co_effs,temperature); co_effs1=polyfit(temperature,cp,3); predicted_cp1=polyval(co_effs1,temperature); %compare my curve…
