Write timetable data to MDF-file



    mdfWrite(mdfFile,mdfData) writes a timetable of MDF data to a new channel group appended at the end of the specified MDF-file. The timetable can also contain channel group and channel metadata, which you can add using the function mdfAddChannelGroupMetadata before performing the write operation. If the file does not exist, the function creates it.

    mdfWrite(mdfFile,mdfData,GroupNumber=chanGrpNum) writes data to the specified channel group index. If unspecified, data is written to a new channel group appended to the end of existing channel groups.
