Thanks I have recently used it, paris_table=table(day,time,sensor,sensor_out), More than likely you don't need to actually build a new table for each; instead use. NB: the import function recognized the datetime first column altho I did have to fix the display format in Excel that seemed to only be time. It would be helpful if you uploaded the table in MAT file, using the paper clip symbol.
