Curve fitting using polynomial equation.

Objective: Aim:To find the best and perfect curve fit for polynomial equations. Program & Explaination: clear all close all clc % preparing the data cp_data = load('data'); temperature = cp_data(:,1); cp = cp_data(:,2); % curve fit % cp = a*T^3+b*T^2+c*T+d co_effs = polyfit(temperature,cp,3); predicted_cp…
