Plotting two loglog y-axes

Is there an equivalent function to plotyy that allows you to plot two different loglog y-axes with different scales using the same x-axis?
For example:
x = [1 2 3 4 5 6 7 8 9 10]
y1 = [2 4 6 8 10 12 14 16 18 20]
y2 = [10 20 40 80 160 320 640 1280 2560 5120]

AX = plotyy(x,y1,x,y2);
set(AX,'yscale','log') % And maybe xscale too?

Thanks Matt. That got me closer. For some reason it's not showing the y-axis tick marks though. Any idea how I can change the scale on just one of the y-axis and show just the points not the lines? It seems the plotyy command always shows the lines.

Yeah, you can play around with different properties of the axes. Try this out, for example:
set(AX,'ytickmode','auto')
And perhaps:
set(AX(1),'ylim',[1 100])
