MATLAB: How to make different points movable in MATLAB

MATLAB

I wanted help in making different point moving with constant velocity. All points should be moving at constant speed.

Use scatter and record the handle . Loop updating the XData and YData properties of the handle and drawnow()

After long 7 month of training and research i reached a success. Here is what i've achieved

clc,clear
px = 5*rand(10,1);         % initial position
py = 5*rand(10,1);
plot(px,py,'.r')
axis([-1 1 -1 1]*20)
hold on
t = 360*rand(size(px));    % initial direction in degree
for i = 1:20               % number of iterations
    dx = 0.5*cosd(t);      % how fast we move
    dy = 0.5*sind(t);
    t = t + 90*(0.5-rand(size(px)));    % change direction (-45:45) degree
    plot([px px+dx]', [py py+dy]')      % plot displacement
    px = px + dx;                       % new position
    py = py + dy;
    h = plot(px,py,'.b');               % plot new position
    pause(0.2)                          % wait
    delete(h)                           % remove new position
                                        % from graph
end
hold off

MATLAB: How can I create a series of same length vectors, extract from each the maximum number, and collect the maximum numbers in a new vector

clc; clear all ;
b=5;
muH=b*sqrt(pi/2);
n=100000; % n different vectors
iwant=zeros(1,n);
for k=1:n  %it creates n different vectors each containing 1000 numbers 
    H= rand(1,1000); 
    h=(muH/mean(H))* H;  %vector  
    iwant(k)=max(h); %extract maximum from each n vectors 
end
