Follow-up Comment #1:

Which part is a bug?  roffset and coffset are used to position the matrix
being written in the destination file.  For example, roffset=1 means one
entire line of delimiters will be written.  A coffset=2 means 2 delimiters
will be prepended to every row written out.

Example


M = [1 2; 3 4];
dlmwrite ('tst.txt', M, ',');
dlmwrite ('tst.txt', M, '-append', 'delimiter', ',', 'roffset', 3, 'coffset',
2);
type tst.txt
tst.txt is the user-defined function defined from: ./tst.txt

1,2
3,4
,,,
,,,
,,,
,,1,2
,,3,4

M2 = dlmread ('tst.txt')
M2 =

   1   2   0   0
   3   4   0   0
   0   0   0   0
   0   0   0   0
   0   0   0   0
   0   0   1   2
   0   0   3   4


Notice how the second matrix portion has been offset from the first as
specified by roffset and coffset.
