Follow-up Comment #4, bug #39505 (project octave):

>>a=[1 2 3 4 5;1 2 3 4 5;1 2 3 4 5];


>> b=[2 3 4 5 6;2 3 4 5 6;2 3 4 5 6]
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);

%leave or try to leave a blank line

>>dlmwrite('matrix_text.txt',a,'-append','on','delimiter',
',','roffset',2,'coffset',0);
