In MATLAB, I plot many different vectors to a figure. Now, what I would like to do is simply undo the last vector that I plotted to that figure, without clearing everything else. How can this be accomplished? Can it be accomplished?

Thanks

Edit:

figure(1); clf(1);
N = 100;
x = randn(1,N);
y = randn(1,N);
z = sin(1:N);
plot(x); hold on;
plot(y,'r');
plot(z,'k');

Now here, I would like to remove the plot z, which was the last plot I made.

If you know before plotting that you want to remove it again later, you can save the handle returned by plot and delete it afterwards.

figure;
h1 = plot([0 1 2], [3 4 5]);
delete(h1);
