Curve fitting

Objective: rsl=0;rsc=0;vs=0; rdata=load(\'data\'); %Reading the data file x=rdata(:,1); %assigning temperature data y=rdata(:,2); %assigning C_p data l=polyfit(x,y,1); %determining and assigning linear coefficients c=polyfit(x,y,3); %determining and assigning cubic coefficients pl=polyval(l,x); %assigning linear C_p data to pl pc=polyval(c,x);…
