It is better practice to load the variables to a struct. Then it is clear where all the data is coming from.
S=load('SI_Aorta.mat');x=S.x;
S=load('SI_Femoral.mat');y=S.y;
poly = polyfit(x,y,n);% n is the order of polynomial
y_val = polyval(poly,x);% find estimated values of y using the polynomial(poly)
figure(1),clf(1)
plot(x,y,'.');
hold on
plot(x,y_val);
hold off
