Curve fitting

Objective: clear all close all clc cp_data=load(\'data\'); temp=cp_data(:,1); cp=cp_data(:,2); coeff=polyfit(temp,cp,2); predicted_cp1=polyval(coeff,temp); coeffs=polyfit(temp,cp,3); predicted_cp2=polyval(coeffs,temp); plot(temp,cp,\'color\',\'b\', \'linewidth\',2); hold on; plot(temp,predicted_cp1,\'color\',\'r\',\'linewidth\',2);…
