t1=0:0.01:1;
i=0;
m1=0;
while(i==0)
    for i=1:99
        y1(i)=1.*t1(i);
    end
    for i= 100:200
        y1(i)=1;
    end
    y=[zeros(1,200+m1) y1 zeros(1,801-m1)];
    %y=y1+y2;
    t2=-2:0.01:10;
    plot(t,y)
    ylim([0 2]);
    xlim([-2 10]);
    m1=m1+200;
    j=input('enter 0 4 times');
end

Could you reshape your code to "easy-to-read" style? Trying copy&past your code to MATLAB, but it does not work.

Souvik - what are you trying to animate? When plot is called, you are passing an invalid parameter t (which doesn't exist). Even if I replace it with t1, it is of a different dimension than y. Please clarify what you are trying to do.

在 MATLAB Online 中打开

If I'm interpreting your question corretly (and fixed your code properly) I faced the same problem years ago: animating plots withing a for/while loop.

Back then I found a solution with two options. The solution is to call Matlab the draw the figure before the next loop, this can be done either by the drawnow command or the pause(s) command, if you would like to lower the drawspeed.

Your script would look like:

t1=0:0.01:1;
i=0;
m1=0;
while(i==0)
    for i=1:99
        y1(i)=1.*t1(i);
    end
    for i= 100:200
        y1(i)=1;
    end
    y=[zeros(1,200+m1) y1 zeros(1,801-m1)];
    %y=y1+y2;
    t2=-2:0.01:10;
    plot(t2,y)
    ylim([0 2]);
    xlim([-2 10]);
    m1=m1+200;
    %drawnow
    pause(0.1)
    i = 0
end
