[x,y,z]=meshgrid(-3:1:3,-3:1:3,-3:1:3);
dx=x;
dy=y;
dz=z;
r=(dx.^2+dy.^2+dz.^2).^0.5;
u=dx./r;
v=dy./r;
w=dz./r;
figure
quiver3(x,y,z,u,v,w)

Simple, make x,y,z matrices as zeros matrix.
[x,y,z]=meshgrid(-3:1:3,-3:1:3,-3:1:3);
dx=x;
dy=y;
dz=z;
r=(dx.^2+dy.^2+dz.^2).^0.5;
u=dx./r;
v=dy./r;
w=dz./r;
x = 0*x ;
y = 0*y ;
z = 0*z ;
figure
quiver3(x,y,z,u,v,w)

quiver3(x-x,y-y,z-z,u,v,w)% i achieve this operation in another way.
