Ran in:
Here's an example:
% a table
T = table([1;2;3],[4;5;6],'VariableNames',{'Time','x'})
T = 3×2 table
Time x ____ _ 1 4 2 5 3 6
% Time column is not duration or datetime
class(T.Time)
ans = 'double'
% try to convert T into a timetable
try
T = table2timetable(T) % error
catch e
disp(sprintf('Error: %s',e.message))
end
Error: Input table must contain datetime or duration vector for row times.
% convert T.Time to durations in seconds
T.Time = seconds(T.Time)
T = 3×2 table
Time x _____ _ 1 sec 4 2 sec 5 3 sec 6
% now Time is duration
class(T.Time)
ans = 'duration'
% and T can be converted into a timetable
T = table2timetable(T)
T = 3×1 timetable
Time x _____ _ 1 sec 4 2 sec 5 3 sec 6
