I'm trying to plot the curl of the function v = -y + x + 0. This comes to (0,0,2), but I get an error stating the variables must be the same size, so I suspect the zeros are causing issues. How can I do a quiver3 plot with these numbers?
%% set up mesh
Xvc=(-5:2:5)';Yvc=(-5:2:5)';Zvc=(-5:2:5)';[X,Y,Z]=meshgrid(Xvc, Yvc, Zvc);%% plot V
Vx=-Y; % Ex 2 Vx from worksheet
Vy=X; % Ex 2 Vy from worksheet
Vz=0; % Ex 2 Vz from worksheet
figure(110)quiver3(X, Y, Z, Vx, Vy, Vz); %Changed to 2D plot due to lack of Vz values
grid onxlabel('Vx')ylabel('Vy')%% compute curl
Crlx=0; %Curl X from solved worksheet
Crly=0; %Curl Y from solved worksheet
Crlz=2; %Curl Z from solved worksheet
figure(120)quiver(X, Y, Z, Crlx, Crly, Crlz);grid ontmp=0;
