Curve fitting using MATLAB

Objective: Aim: To write Matlab code for curve fitting Code for the curve fitting clear all close all clc cpdata= load('data'); temp = cpdata(:,1); cp = cpdata(:,2); plot(temp,cp,'linewidth',4) hold on abc = polyfit(temp,cp,3); dupcp = polyval(abc,temp); abc = polyfit(temp,cp,1); ducp = polyval(abc,temp);…
