Hi,

By using sum function I want to sum up the values in a vector, the results should be 14,532,000 but I get NaN. How can I avoid to get NaN? How can I get 14,532,000 instead of NaN. The vector can be shown, however I cannot get result of summation.

Thank you in advance.

Regards,

Ozge

x = [4 5 6 NaN 10 3];
sum(x(~isnan(x)))  % Compare to sum(x)

in addition - and - if(f) you own the stats tbx

     help nanmean;     % <- and siblings...

Hi,

Thank you for your interest. But I have no NaN value in my vector. I get NaN as a result, however when I export my vector to Excel and sum the values in the vector I get 14,532,000. The point that I do not understand is why I get NaN instead of 14,532,000 from Matlab. I want to do something and get the exact result instead of NaN. Thank you.

O.k., so what do you get for this:

any(~isfinite(x))  % replace x with your vector.
