Hello,
I am trying to visualize the vector field function
F(x,y,z) = xz * i + xy * j + 3xz * k
with Matlab (2020b).
I tried quiver3, but the examples were not really helpful.
Thanks in advance for help!
Best,
Felix

x = -3 : 0.5 : 3;
y = -3 : 0.5 : 3;
z = -3 : 0.5 : 3;
[xx,yy,zz] = meshgrid(x,y,z);
Fx = xx.*zz;
Fy = xx.*yy;
Fz = 3*xx.*zz;
figure
quiver3(xx,yy,zz,Fx,Fy,Fz)
