When I combine 2 timetables horizontally, error always occurs. How can I manage to combine them?

The 2 timetables (a and b) have the same time rows but different variable arrays:

a =

5×1 timetable

Time ID1S01_PWM_timerticks_ph1

__________ _________________________

4.2981 sec 0

4.303 sec 65534

4.3081 sec 0

4.3131 sec 0

4.3181 sec 0

b =

5×1 timetable

Time ssiSelSicMsg2

__________ _____________

4.2981 sec 9

4.303 sec 9

4.3081 sec 9

4.3131 sec 9

4.3181 sec 9

>> [a b]

Error using tabular/horzcat

All tables being horizontally concatenated must have the same row times.

在 MATLAB Online 中打开

Experiment with the synchronize function to see if it will do what you want.

To illustrate —

Time = [4.2981; 4.3030; 4.3081; 4.3131; 4.3181];
ID1S01_PWM_timerticks_ph1 = [0; 65534; 0; 0; 0];
T1 = timetable(seconds(Time),ID1S01_PWM_timerticks_ph1)
T1 = 5×1 timetable
       Time       ID1S01_PWM_timerticks_ph1

ssiSelSicMsg2 = 9*ones(5,1);
T2 = timetable(seconds(Time), ssiSelSicMsg2)
T2 = 5×1 timetable
