Follow-up Comment #3, bug #39505 (project octave):
Bug was re-opened. What is the actual problem? dlmwrite seems to be
respecting the documentation regarding inserting delimiters if roffset or
coffset is used. The Mathworks documentation is here
(http://www.mathworks.com/help/matlab/ref/dlmwrite.html).
I changed the sample code to use a comma as the delimiter so that I can see
what is going on.
a=[1 2 3 4 5;1 2 3 4 5;1 2 3 4 5];
dlmwrite('matrix_text.txt',a,'-append','on','delimiter',
',','roffset',0,'coffset',0);
b=[2 3 4 5 6;2 3 4 5 6;2 3 4 5 6];
dlmwrite('matrix_text.txt',b,'-append','on','delimiter',
',','roffset',0,'coffset',0);
dlmwrite('matrix_text.txt',a,'-append','on','delimiter',
',','roffset',1,'coffset',0);
dlmwrite('matrix_text.txt',a,'-append','on','delimiter',
',','roffset',2,'coffset',0);
dlmwrite('matrix_text.txt',a,'-append','on','delimiter',
',','newline','unix','roffset',3,'coffset',0);
dlmwrite('matrix_text.txt',a,'-append','on','delimiter',
',','newline','unix','roffset',4,'coffset',3);
If I then read the file back in with dlmread all of the test matrices are in
their proper positions.
"z
x = dlmread ('matrix_text.txt', ',')
x =

I'm attaching the actual file generated as matrix_text.octave.txt. If you
have access to Matlab you could run the code in this comment and compare the
generated file to matrix_text.octave.txt. If there is a difference then we
can look into it, but Octave appears to be following the documentation
correctly.
