curvefit

Objective: clear all close all clc %preparing the data cp_data = load (\'data\'); temperature = cp_data(:,1); cp = cp_data(:,2); %curvefit %cp=a*T^3+b*T^2+c*T+d %cp=a*T+b co_effs = polyfit(temperature,cp,3); co_effs1 = polyfit(temperature,cp,1); predicted_cp = polyval(co_effs,temperature); predicted_cp1 = polyval(co_effs1,temperature);…
