Hello all, I have a problem with my code. I get incorrect results when in dataset are some 'inevitable' missing value. How can I do? I don't want to remove them. Do you have any idea? Thank you, Doriana

I can't filter out the NaNs. I have to estimate the missing values. I can use Intepolation?

This question must be answered by you. You seem to make some statistics and I'm not sure if interpolation makes a lot of sense in this context. If you think it does make sense, you can use the following lines (1D only):
function y = interp1_nan(x,y)
y(isnan(y))=interp1(x(~isnan(y)),y(~isnan(y)),x(isnan(y)),'linear','extrap');
