Is there a command to plot unit vectors in 3D?

I have 3 unit vectors like (1,0,0) (0,1,0) (0,0,1), and I want to plot them in 3d with same origin. I tried command "plot3" but seems like it just link those dots for me

E.g.,

point1 = [1,0,0];
point2 = [0,1,0];
point3 = [0 0 1];
origin = [0,0,0];
figure;hold on;
plot3([origin(1) point1(1)],[origin(2) point1(2)],[origin(3) point1(3)],'LineWidth',5);
plot3([origin(1) point2(1)],[origin(2) point2(2)],[origin(3) point2(3)],'LineWidth',5);
plot3([origin(1) point3(1)],[origin(2) point3(2)],[origin(3) point3(3)],'LineWidth',5);
grid on;
xlabel('X');
ylabel('Y');
zlabel('Z');
set(gca,'CameraPosition',[2 2 2]);

point1 = [1,0,0];
point2 = [0,1,0];
point3 = [0 0 1];
origin = [0,0,0];
p = [origin;point1;nan(1,3);origin;point2;nan(1,3);origin;point3]
plot(p(:,1),p(:,2),p(:,3))
