Hi, thanks for the comment.
you're correct with the "b".
Right, point would speed up writing, however, comma as decimal seperator was needed for the specific problem (external program usage).
On my machine a cellarray (1e6x4) with one string column and three data columns needs 118s to export with "W" and >>118s with "w" (stopped export after 15 minutes). I'm not that deep into low level file stuff, but this was a strong argument...

FOPEN ignores the "b" format. The binary mode is enabled when the format does not contain a "t" - see "help fopen". Why do you use uppercase "W" instead of "w"? Automatic flushing is efficient.
Why do you use a comma as decimal separator instead of the dot? This will impede the reading substantially.
