How can I interpolate this row?

Hi Everyone, I would like to get your help to interpolate this vector: x=[2 NaN NaN 5 NaN NaN] to fill the messing values

Thanks in advance

Do you have an estimation of the function that should be used? Because if it is anything other than linear, you have too few values.

No. Do you know how can I interpolate one like this[2 3 4 5 NaN NaN]?

Check if the fillmissing function does what you want. https://mathworks.com/help/matlab/ref/fillmissing.html

Thank you for your response, I tried to use "fillmissing" but I got this sentence "Undefined function or variable 'fillmissing'" It is weird, since I am using matlab 2015!

You don't have the associated license.

try something like :

nanx = isnan(x);
t    = 1:numel(x);
x(nanx) = interp1(t(~nanx), x(~nanx), t(nanx));
