Error when using timetable/retime

I make a script that describes when EVs are charging during one year. I loop it for 429 cars.

However when car 8 is up this segment errors:

T=[];

%Create a time table which says what minute of the year that the car charges

for zeus=1:length(Chargingprofile)

if Chargingprofile(zeus,1)>0

x = [Chargingprofile(zeus,1) Chargingprofile(zeus,3); Chargingprofile(zeus,2) 0];

x = [x];

Tkk = timetable(minutes(x(:,1)),x(:,2));

Tkk.Var1(1:end-1) = Tkk.Var1(1:end-1) ./ minutes(diff(Tkk.Time));

Tkkk = retime(Tkk,'minutely','previous');

T=[T; Tkkk;];

end

end

-----------------

displaying this

Error using timetable/retime (line 140)

Interpolation requires at least two sample points in each dimension.

Error in MAIN (line 1148)

Tkkk = retime(Tkk,'minutely','previous');

---------------------

Tkk looks like this:

'1068 min' NaN

'1068 min' 0

I know that Tkk should look differently, NaN should be 0.1833 (as for all other cars) and the left column should contain a higher and a lower time value, but I dont know how to troubleshoot further

Running these two commands did not give me an error:

t=timetable(minutes([1068;1068]) ,[NaN;0])
retime(t,'minutely','previous')

Are you seeing an error with these same two commands? If yes, which version of MATLAB are you on?

If you aren't running into an error with the two commands I just posted, could you share any simple reproduction steps for your error?

Ah, I had a second look. This is a known bug and is reproducible in R2019a. It was fixed in R2019b.

You could try one of two things:

1. Make sure you don't send a NaN value into retime.
2. Upgrade to a newer version of MATLAB.
