Hi there
Im trying to do a running mean of a quite large wind-direction data-set but I'm having trouble finding solutions that work. Does anyone know of a simple solution?
Thanks in advance

You could look at the excellent "Circular Statistics Toolbox"

- how can i use mean angle?
- M = xlsread('Dic2019','Dic2019mat')
- ten_minute_avarege = meanangle(reshape(M, 10, []), 'omitnan')
- xlswrite('datosexcel1.xlsx', ten_minute_avarege, 'Hoja1', 'A1');

I am not aware of any meanangle() function that has 'omitnan' as an option.

Note that unwrap assumes your angles are in radians. If you're using degrees (and from the 360 in your code I think you are), multiply your data by pi/180 before using unwrap. You can convert back afterwards if necessary by multiplying by 180/pi.
Also, perhaps there's a problem with runmean. Maybe you could explain a little more about what this function does, or if it's very short even copy it into your question. (Not into a comment or answer though.)
