simulate sinusodial graphs in matlab

My today's question is how to simulate continuously some graph in matlab? For example: let us consider the following simplest code

x = 0 : 0.1 : 10;
z = sin(x);
plot(x,z), grid

When I run this code, I get usually sin function graph, whose figure is given below enter image description here

Actually, what I need is, that the graph is static, i.e. that it does not move. What I want is that simulate this graph, namely appears on window, disappears and then again repeat this procedure, as I guess I need loop for this, but maybe there is some built-in function for simulation graphs in matlab? Please help me

Do you mean that you want to animate this graph? MATLAB offers numerous ways to do that.

One of the simplest would be generating a short movie frame-by-frame using getframe and then playing it with the movie command. For example:

%// Generate movie
x = 0:0.1:10;
FRAMES = 32;                  %// Total number of frames
for k = 1:FRAMES
    ph = k * 2 * pi / FRAMES; %// Accumulate phase
    plot(x, sin(x + ph))      %// Generate plot
    grid, axis equal
    M(k) = getframe;          %// Capture frame
end

%// Play movie 10 times
movie(M, 10)
