Hi. I am using retime to get quarterly mean data from irregularly distributed measurements:
yTT = retime(xTT,'quarterly',@nanmean);
My first measurement is on the 1st of April. The new yTT timetable has now timesteps at April, July, September, and January. My question is now are these quarterly values means of the widely used Mar-Apr-May, Jun-Jul-Aug, Sep-Oct-Nov, and Dec-Jan-Feb? Or is the April quarterly value an average of Apr-May-Jun, and so on?
