Plotting Error Bars (Uncertainties) for Scatter Plot Points

Shown in my code below, I am calculating a vector of drag coefficients and a vector Reynolds number, and then a calculation of their uncertainties (i.e., Re+/-unc). How do I plot the vertical and horizontal error bars representing the vectors I have calculated below in the code (u_C_D and u_Re). C_D is the y-variable, Re is the x-variable, so u_CD error bars need to be going vertical, and the u_Re error bars need to be horizontal.

Thanks!

V = [5,6,7,8,9,10,11,12,13,14,15]; % Velocity Data in m/s
F = [8.6,11.8,15.9,20.5,25.5,31.4,37.9,45.2,53.5,61.3,70.4]; % Drag Force in mN
p = 1.16; % Density in kg/m^3
D = 25; % Diameter of Disk in mm
m = 18.4e-6; % Viscosity in Ns/m^2
uV = 0.3; % Velocity uncertainty in m/s
uF = 0.1; % Force uncertainty in mN
up = 0.01; % Density uncertainty in kg/m^3
uD = 0.05; % Diameter uncertainty in mm
um = 0.1e-6; % Viscosity uncertainty in Ns/m^2

Re = p*V*D*10^-3/m; % Calculation of Reynolds Numbers
CD = 2*F*10^-3./(p*V.^2*pi/4*(D*10^-3)^2); % Calculation of Drag Coefficients

% Calculation of uncertainties in C_D and Re
uRe = Re.*sqrt((up/p)^2+(uV./V).^2+(uD/D)^2+(um/m)^2);
uCD = CD.*sqrt((uF./F).^2+(up/p)^2+(2*uV./V).^2+(2*uD/D)^2);

figure(1)
plot(Re,CD,'*')
grid on
xlabel('Drag Coefficient, C_D');
ylabel('Reynolds Number, R_e');
