Hello,
There is a bug in dlmwrite in the current io pcakage regaring
text/binary file open mode.
Currently the file is opened in text mode, which implies automatic
LF->CRLF translation under windows.
But the line endings to be used are explicitly specified and determined
by the option "newline".
So if "newline" is set to "pc", "\r\n" will be written to the text file,
which is translated into "\r\r\n", since the file is opened in text mode.
So the openmode should be binary.
