[Octave-bug-tracker] [bug #39505] dlmwrite with coffset and roffset >0, inserts extra characters

[imartinez]

Follow-up Comment #16, bug #39505 (project octave):

Calm down, Philip Nienhuis.... it needs several cases to check 
what is going on.

in matlab with tabs first and then with commas...

dlmwrite('matrix_test.txt',a,'-append','delimiter',
't','roffset',0,'coffset',0);
>> dlmwrite('matrix_test.txt',b,'-append','delimiter',
't','roffset',0,'coffset',0);
>> dlmwrite('matrix_test.txt',b,'-append','delimiter',
't','roffset',4,'coffset',0);
>> dlmwrite('matrix_test.txt',b,'-append','delimiter',
't','roffset',4,'coffset',4);
>> dlmwrite('matrix_test.txt',b,'-append','delimiter',
',','roffset',0,'coffset',0);
>> dlmwrite('matrix_test.txt',b,'-append','delimiter',
',','roffset',1,'coffset',0);
>> dlmwrite('matrix_test.txt',b,'-append','delimiter',
',','roffset',2,'coffset',0);
>> dlmwrite('matrix_test.txt',b,'-append','delimiter',
',','roffset',3,'coffset',0);

Tabs are ok in matlab, empty lines are generate when you open the file in
wordpad. This is what a microwave S2P file needs

I do recognize that with commas, it is inserting commas on the blank lines.

So, I think it still holds water at about 50%
