Convert an array to a timetable. Add a vector of durations as the row times.

X = rand(5,3); Time = [seconds(1):seconds(1):seconds(5)]; TT = array2timetable(X,'RowTimes',Time)
TT=5x3 timetableTime X1 X2 X3 _____ _______ _______ _______ 1 sec 0.81472 0.09754 0.15761 2 sec 0.90579 0.2785 0.97059 3 sec 0.12699 0.54688 0.95717 4 sec 0.91338 0.95751 0.48538 5 sec 0.63236 0.96489 0.80028

Return the size of the timetable.TTcontains five rows and three variables. The set of row times is a table property. The row times are not contained in a table variable.
