I created a simple timetable with a time variable t_HR in datetime format and a HR variable in double format;
HR_TT = timetable(t_HR,HR);
head(HR_TT)
ans =
8×1 timetable
t_HR HR

I am trying to resample the data (there is irregular sampling) using retime, but don't want NaN values when interpolating or resampling.
Therefore I want to change the timetable property VariableContinuity to 'continuous'.
I tried accessing the timetable properties but the following error appears:
HR_TT.Properties
ans =
Matrix index is out of range for deletion.
Error in matlab.internal.datatypes.DisplayHelper/printToScreen (line 167)
t(logical(obj.isloose*[1 1])) = [];
Error in matlab.tabular.TabularProperties/disp (line 51)
h.printToScreen(name,false);
Could anyone help with this?
Many thanks

Could you attach a mat file containing your variables?
I wasn't able to reproduce your error using made up data.

Here is a truncated version.
I tried making different timetables with different kinds of data, but the error is the same.
Thank you

Something is not working correctly on your computer. Try restarting MATLAB. If it still happens, try restarting your computer.
For sanity checking, if you have access, run the same command in MATLAB Online (if you have access).
If the problem continues on your computer, you many need to try reinstalling MATLAB.

The same data set is used to access the properties and error seems non- reproducible.
The highlighted property, as shown in the screenshot, can be changed by
>> HR_test.Properties.VariableContinuity = {'continuous'}

This does not happen with my machine, however. I am running Matlab R2019b for Mac.
And running the command you mention:
>> HR_test.Properties.VariableContinuity = {'continuous'}
Does not affect the way the interpolation is then made (there are still the same number of NaNs).
In fact, this problem extends to tables in general: see screenshot
