syms u v
atan2alt(v,u)
function Z = atan2alt(V,U)
% extension of atan2(V,U) into the complex plane
Z = -1i*log((U+1i*V)./sqrt(U.^2+V.^2));
% check for purely real input. if so, zero out the imaginary part.
realInputs = (imag(U) == 0) & (imag(V) == 0);
Z(realInputs) = real(Z(realInputs));
end
As I am editing this post, I see the expected symbolic display in the nice form as have grown to love. However, when I save the post, it does not display. (In fact, it shows up here in the discussions post.) This seems to be a new problem, as I have not seen that failure mode in the past.
You can see the problem in this Answer forum response of mine, where it did fail.

FYI, this issue has been fixed. Thank you for your patience as we were trying to find a solution to address this issue.
After a quick experiment, it appears that any old answer or comment on Answers has to be reopened with an edit and then resubmitted for the symbolic output to show up. It doesn't have to be rerun, just resubmitted.
Yes, if the symbolic output exists in the editor from previous run, just resubmitting the post will make them appear.
Can you give us a status on this? Can we expect the desired functionality to return in the near future or is this going to be long term issue?
And again, several days later, it had been working fine. But today, broken again.
Darn. It was working too, for a few days. But again, it is broken as of today.
Hi @John D'Errico, this is a bug on our end that is preventing symbolic outputs from getting displayed in the outputs. So clearing the cache or changing browsers won't help. We are still investigating to find the root cause to fix it.
ARGH!
This happens on a daily basis to me.
And today, even doing as I described did not fix the problem. That is, clear all caches. delete all history. Quit the browser, restart (safari.) Multiple times emptied caches. Then I tried using firefox, so a totally different browser. Nothing fixes it. And it breaks daily, even when eventually it does work.
Even changing browsers did not fix it today. And I've gotten no response from @Tushal Desai
And now it is working. Along the way, I
- Restarted
- Empty caches
- Clear history
But it did finally work.
