Visualize a vector field function with matlab

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)

Alright, thank you very much!
