MATLAB: I am trying to create a normal random moving point for each individual point in a 3D scatter point. How to go about to do this

3dgaussianMATLABscatter

I am trying to replicate the random movements (gaussian distribution) found in particles and to do that, I have already made a moving plot (in a normal random distribution) but I am trying to have a maybe 5 by 5 number of points with each point having its on random moving point.
Code attached are the moving plot and the scatter plot

What about this?
n = 5;
[X,Y] = meshgrid(1:n);              % create mesh
T = 180*rand(n)-90;                 % initial angles
cla
plot(X(:),Y(:),'ob')                % plot starting points
hold on
for i = 1:30
    T = T + rand(n)*90 - 45;        % increase/decrease angle
    X = X + 0.05*cosd(T);           % increase/decrease X coordinate
    Y = Y + 0.05*sind(T);           % increase/decrease Y coordinate
    plot(X(:),Y(:),'.r')            % plot new coordinates
    pause(0.1)
end
hold off
