Follow-up Comment #4, bug #60671 (project octave):
I don't see the necessity of loops here. eomday does allready calculate the
last of month. Could you please post your fix as a complete file?
Here is the excerpt from my fix (see full file in attachments)
## adjust the years and months if the date rolls over a year
dtmp(:,1) += floor ((dtmp(:,2)-1)/12);
dtmp(:,2) = mod (dtmp(:,2)-1, 12) + 1;
# BUGFIX gwiora: Avoid days beyond end of month
beyondEOM = dtmp(:,3)>eomday(dtmp(:,1),dtmp(:,2));
dtmp(beyondEOM,3) = eomday(dtmp(beyondEOM,1),dtmp(beyondEOM,2));
