It is a simple doubt, but I am unable to resolve it. How can I plot these 3 functions together so that I can see them in full? do i really have to use meshgrid and contour?
[x1,x2]=meshgrid(-2:.1:4, -2:.1:4);cost=x1.^2 + x2.^2 - 5*x1 - 6*x2 + 15;contour(x1,x2,cost,1,'g','LineWidth',1)figure(1)y=2*x1.^2 + 2*x2.^2 - 3*x1 - 3*x2 - 2;z=x1.^2 + x2.^2 - 4*x1 - 3*x2 + 8;hold oncontour(x1,x2,y,1,'k','LineWidth',1)contour(x1,x2,z,1,'k','LineWidth',1)xlim([-2 4])ylim([-2 4])
currently my result is this:
and I need it to be like this:
