MATLAB: Data with NaN

Question

Hi

I´m having trouble plotting data that include NaNs. I load a data-matrix using textread. I want to skip plotting entries that are NaNs.

For example:

x=[4 2 NaN 9]

y=[3 5 7 8]

Now I want to plot x against y for the 1st, 2nd and last entries (skipping the third). Are tips how to do this?

Answer 1

If you wanted to keep a line connecting them:

I = ~isnan(x) & ~isnan(y);
plot(x(I),y(I))
