Accepted Answer

c1=polyfit(x,y,1); c2=polyfit(x,y,2); norm(polyval(c1,x)-y); norm(polyval(c2,x)-y)

Answer

c1=polyfit(x,y,1); c2=polyfit(x,y,2); norm(polyval(c1,x)-y,1); norm(polyval(c2,x)-y,inf)

Answer

c1=polyfit(x,y,1); c2=polyfit(x,y,2); norm(polyval(c1,x)-y); norm(polyval(c2,x)-y,1)

Answer

c1=polyfit(x,y,1); c2=polyfit(x,y,2); norm(polyval(c1,x)-y,inf); norm(polyval(c2,x)-y,inf)

Answer

c1=polyfit(x,y,1); c2=polyfit(x,y,2); norm(polyval(c1,x)-y,1); norm(polyval(c2,x)-y,1)
