Comparing Data sets with same numbers of Array
5 views (last 30 days)
I have 2 data sets which I would like to compare. Both data sets have 92 values (or 92 days of data).
My first Data set is categorial wind direction. My second data set is numerical values (carbon concentration).
I would like to be able to determine, for example, in the first data set where say day 1, 5, 10, 15, 50, 60, 92 had winds of N-NE, what are the corresponding values in the 2nd data set (carbon concentration).
And then make a mean of the carbon concentrations when winds were blowing N-NE.
I've attached my data,
Any help would be much appreciated!

As you have no N-NE direction, here is an example for SE-S:
dayId = [1, 5, 10, 15, 50, 60, 92] ;
cat_sub = cat_wind_direction(dayId) ;
s_cf_sub = s_cf_day(dayId) ;
mean_cf = mean( s_cf_sub(cat_sub == 'SE-S') )
Let me know if you have any question.
