Hello guys.
I am trying to achieve something easy I think, but I don't know the correct way.
I have two tables, let's say WRF and Obs, that contain hourly values of several variables. What I want to do is calculate things and produce graphs, for the dates that both tables have data.
Eg, WRF contains data from 1/7/2019 to 30/9/2019 and Obs from 31/3/2019 to 30/9/2019.
I tried
ismatch = ismember(Obs.Hourly_DATE, WRF.Date);
which returns 0s kai 1s. How do I take one step further and use the 1s to calculate the things I want?
Thank you in advance!

Ok the innerjoin should then correctly merge the two tables together on the common datetime values. Do verify the newtable created before using it further.

Yes needed to combine with the time column.
load Obs.mat
load WRF.mat
WRF_Data.Date = WRF_Data.Date + duration(hour(WRF_Data.Time),minute(WRF_Data.Time),0)
Obs_Data.Hourly_DATE + duration(string(Obs_Data.Time),'InputFormat','hh:mm');
newtable = innerjoin(Obs_Data,WRF_Data,'LeftKeys','Hourly_DATE','RightKeys','Date');
