Read MDF-file format from a channel group number using the readDatasetFromGroupNumber function.

Create a file path.

filePath = fullfile(pwd,'dataSetMdf.mdf');

Create multiple data sets.

ds = Simulink.SimulationData.Dataset;
ds = ds.addElement( timetable(seconds([1;2]),[1;2]),'X');
ds = ds.addElement( timetable(seconds([1;2]),[1;2]),'Y');
ds = ds.addElement( timetable(seconds([1;2]),[1;2]),'Z');

Export the data sets to MDF format.

anMDF_FileType = Simulink.io.MDF;
anMDF_FileType.export( filePath, {'group1' 'group2'},{ds ds},0)
anMDF_FileType.export( filePath, {'group1' 'group2'},{ds ds},0)
