How to remove a signal from a timeseries (the signal is known and the same length as timeseries)

I have a timeseries of length 35. I want to remove a signal from this timeseries. The signal I want to remove is another timeseries also of length 35.

The image link:

shows the two timeseries plotted as a plotyy(). How would I go about removing the signal of 'timeseries B' from 'timeseries A'. I am implying that 'timeseries B' makes up part of 'timeseries A' as noise.

Thanks

Look at this example

t=0:0.1:10
y1=sin(t)
y2=t.^2
plotyy(t,y1,t,y2)
h=findobj(gcf,'type','axes')
delete(h(1))

Hi there, thanks. I dont just want to remove the signal from a plotyy() plot. How would I remove the signal if simply the timeseries A was shown. I am implying that timerseries B makes up (as noise) part of timeseries A

Please, make your question clear. have you one signal or two? The plot shows two signals, maybe you should show us another plot, to better illustrate what you want.

Oliver, how are your data stored? If B is a noise component of A that you want to remove, can you not just compute C = A - B? You can do this if A and B are double vectors; you can also do it if they are timeseries objects.
