Hi, I just want to graph the curl of this vector field:
F(x,y)=-2x ay % just have y direction not x.
Manually the curl gives me: -2 az, but when using the curl function in matlab it gives me -1 (a constant plane in z=-1), why? It suppose to give me a constant plane in z=-2.
code:
[x,y]=meshgrid(0:0.1:5, 0:0.1:5);
Fx=0.*x;
Fy=-2.*x;
rot=curl(x,y,Fx,Fy);
mesh(x,y,rot)
