plot vectors of different lengths

I have two vectors, say x and y, with lengths 100 and 200 respectively. I'd like to plot them separately, but in the same figure and at the same scale. I can get them in the same figure with the following:

> subplot(2,1,1); plot(x);
> subplot(2,1,2); plot(y);

But this stretches both to fill the width of the window, so the scale for the plot of x is double that of the scale for y. How do I get the plots to use the same scale, so that the plot for x takes up half the width of the plot of y?

Thanks.

Is this what you mean?

subplot(2,1,1), plot(1:10)
set(gca,'XLim',[0 20])

subplot(2,1,2), plot(1:20)
set(gca,'XLim',[0 20])

Not exactly. I'm trying to produce a plot like the one here:

Using my code or yours, it stretches each plot out to the width of the window. I'd like to not have them stretched out.

Thank you!

This "answer" would be better understood if you either edited your question to include this info, or just placed it as a comment on my (incorrect) answer.

Here is one way. You'll need adjust the position parameters to get exactly what you want, but that shouldn't be too hard.

figure
subplot('Position',[0.1 0.55 0.8 0.4]),plot(1:20)
subplot('Position',[0.1 0.05 0.4 0.4]),plot(1:10)

You might want to read "doc subplot". In particular, note that if you position a set of axes such that the overlap an existing one, the existing one will be deleted.
