animate

Say I have a 3×3 matrix, I want to plot the 3 columns in animation. Meaning plotting the column values 1 after the other. Any idea please. Thanks for the help.

M = rand(3, 3);
figure;
axes('XLim', [1, 3], 'YLim', [0, 1])
H = line(1:3, inf(1, 3));
for k = 1:3
  set(H, 'YData', M(:, k));
  pause(1);
end

You can use the comet() function if you manipulate the data a bit.

x=[0:1:10]; 
a=[0 1 0 1 0 1 0 0 1 1 0];
xq=0:0.01:10;
aq = interp1(x,a,xq,'previous');
comet(xq,aq)

There is also a similar function called animatedline() which I have never tested. Or as a third, perhaps simplest solution, plot point-by-point in a for-loop using pause(t) in every loop.

If you have MATLAB R2014b or later, you can use animatedLine

For earlier versions you can use scatter() or plot(), updating the XData and YData properties as you go. For example,

x = []; y = [];
pointsize = 30;
h = scatter(x, y, pointsize, 'k');
for K = 1 : 20
  newx = rand(); newy = rand();
  x(end+1) = newx;
  y(end+1) = newy;
  set(h, 'XData', x, 'Ydata', y);
  drawnow();
end

But my guess is that you might be looking for Psychophysics Toolbox
