Hi Yevgeniy, the error arises because logical values do not support missing values, which 'extractTimetable' tries to handle using the 'fillwithmissing' option.
To address this, you can try the following steps:
- Convert Logical Signals to a Compatible Format: Before logging, you can convert logical signals to a format that supports missing values, such as double or categorical. This way, 'extractTimetable' can handle them properly. After extraction, you can convert them back to logical if needed.
- Custom Extraction Function: Create a custom function to manually extract and synchronize the signals without using the default 'extractTimetable' method. This function can handle logical signals appropriately.
An example of how you might implement the first approach is as follows:
% Convert logical signals to double before logging
% Assuming 'simout' is your simulation output
for i = 1:numel(simout.logsout)
if islogical(simout.logsout{i}.Values.Data)
simout.logsout{i}.Values.Data = double(simout.logsout{i}.Values.Data);
end
end
% Now use extractTimetable
timetableData = extractTimetable(simout.logsout);
% Convert the signals back to logical if necessary
for i = 1:width(timetableData)
if all(ismember(timetableData{:, i}, [0, 1]))
timetableData{:, i} = logical(timetableData{:, i});
end
end
For the second approach, you can manually extract the signals and synchronize them without using 'extractTimetable':
% Manually extract and synchronize signals
signals = simout.logsout;
time = signals{1}.Values.Time;
data = arrayfun(@(s) s.Values.Data, signals, 'UniformOutput', false);
names = arrayfun(@(s) s.Name, signals, 'UniformOutput', false);
% Create a timetable
timetableData = timetable(time, data{:}, 'VariableNames', names);
% Synchronize manually if needed
% Assuming no missing values, just concatenate
% timetableData = synchronize(timetableData, 'union', 'fillwithconstant', NaN);
% Convert back to logical if necessary
for i = 1:width(timetableData)
if all(ismember(timetableData{:, i}, [0, 1]))
timetableData{:, i} = logical(timetableData{:, i});
end
end
By using one of these approaches, you should be able to log your logical signals into a single timetable without encountering the synchronization issue. Hope this helps!
