Input timetable must be regular with respect to absolute time, or a time unit supported by isregular. For details, see <a href="matlab:doc('isregular')">isregular</a>. Input timetable must be regular with respect to {0}. Lag interval must be a scalar integer, duration, or calendarDuration. Lag interval must be a multiple of input timetable's time step. Use RETIME to interpolate timetable variables at times that fall between the row times. Lag interval for timetable with duration row times must be a scalar integer or duration. calendarDuration lag interval must be an integer multiple of either calendar months, calendar days, or time.
