Is Code Not Running on Answers?

Is code not running on Answers? Every time I hit the run button, the page hangs with the red square instead of the greeen triangle in the Run secition of the toolbar. Anyone else having the same problem?

They have been having problems for weeks. This is just the latest incarnation. But yes, the red square of code death has been seen on my computer too.

[DGM]

Yeah. The edit box occasionally escapes the center column and overlaps with the sidebar too. Can't get it to consistently do it though.

[Rena Berman]

(Answers Dev) @Paul, I will report this internally and see if we have any updates on this. Thanks for reporting it.

[John D'Errico]

I've been reverting to almost always running all code on my machine, then using copy/paste to insert results, like the old days. It works always, even though I don't get the pretty symbolic formatting.

[Rena Berman]

(Answers dev) Hi, @Paul, @John D'Errico, @DGM, a fix was released late yesterday and you should be able to run code after clearing your browser cache.

Confirming the run capability:

a = 3

a = 3

b = 4

b = 4

a+b

ans = 7

[Paul]

Still not working for me after clearing browser cache (and only the cache), closing Edge, and then opening Edge. Win 10.

[Star Strider]

It’s not working for me either.

Cleared my Firefox browser cache and refreshed this page. (I only use Firefox for Answers.)

epi = exp(pi)

This doesn’t execute. (The red ‘Busy’ square appears in the top toolbar and never changes.)

.

[Rena Berman]

(Answers dev) I'll report this...

epi = exp(pi)

epi = 23.1407

works for me

[Rena Berman]

(Answers dev) @Star Strider can you confirm if you cleared the cache as suggested here https://support.mozilla.org/en-US/kb/how-clear-firefox-cache#w_clear-the-cache ? can you try running the code again?

[Rena Berman]

(Answers dev) @Paul can you confirm if you cleared the edge cache as suggested here https://confluence.atlassian.com/bbkb/how-to-clear-browser-cache-for-chrome-edge-firefox-and-safari-1206562212.html and then try running code again?

[Stephen23]

x = exp(pi)

It is not working for me. The browser tab shows "Executing..." forever, nothing else happens.

[John D'Errico]

@Rena Berman

A test just now shows it worked. The red square of code limbo is gone today!

x = exp(pi)

x = 23.1407

[Star Strider]

@Rena Berman — I used exactly that Firefox page and proceedure.

epi = exp(pi)

epi = 23.1407

I just did it again to be sure, and I can now run that line of code here! (I couldn’t a couple minutes ago, though. Maybe it takes a bit of time?)

I have Edge open, however I don’t use it for anything related to MathWorks, and I can’t access that option in the link because it doesn’t exist in Edge for me. (I’m not logged in to Edge or Micro$oft on this machine.) It doeesn’t seem to be relevant to this problem, anyway.

SUCCESS! (At least for me ...)

.

[Rena Berman]

(Answers dev) @Stephen23 can you refresh your page and try one more time? I'm wondering if there is something amiss with the first try after clearing one's browser cache but then the second one works.

[Stephen23]

x = exp(pi)

x = 23.1407

Cleared history and cache, now it works (fyi: clearing the cache in the last few days did not work).

[Star Strider]

On a different note, can we have the symbolic results back?

They currently exist only when doing the symnbolic computations, and disappear after submitting a post.

.

[Torsten]

@Rena Berman

Usual code running seems to work now, but display of results from symbolic computation after submitting a post is still not working.

[Rena Berman]

(Answers dev) @Stephen23, a fix was released late yesterday so clearing the cache before then would not have helped. @Star Strider, we are working on the symbolic results.

[Rena Berman]

(Answers dev) @Torsten, @Star Strider, I'm told it might take a week or so for the symbolic results part to be fixed.

[Star Strider]

‘I'm told it might take a week or so for the symbolic results part to be fixed.’

Thank you for looking into that!

Just out of curiosity, is there a specific reason for all the recent problems? Is this all part of a general upgrade of some sort?

[Rena Berman]

(Answers dev) @Star Strider, yes, there was an upper level navigation update for many parts of mw.com. Some Answers features broke with the updates.

[Paul]

@Rena Berman

I did follow the intrusctions in that link. Just tried it again AND cleared out temporary internet files for Internet Explorer. Not sure if the latter mattered (don't know why it would, I don't use IE), but it's now working for me.

exp(pi)

ans = 23.1407

As the scope of this thread has expanded, I'll also note that:

The link at the top of the page for the most recent activity on a thread no longer works. As I type this, the top of this thread shows:

"Commented: Rena Berman (Staff) about 2 hours ago"

Clicking on the Commented link doesn't take me to your comment, in fact it doesn't take me anywhere.

Also, I've notice that the @doc functionality seems to be mangled as well. The "Search in Documentation" list is not displaying correctly. I might be able to post a screen cap if needed.

More generally, might it be useful to have a link on the Answers front page that lists current, known issues with Answers functionality, like the symbolic stuff not rendering and other things mentioned in this thread? And maybe that link would provide a means to report observed issues that are not currently listed. It could even be a link that could be "followed" so users can get up to date information as the developers add or remove things from the list when they've been fixed.

[Walter Roberson]

I reported the @doc problem yesterday; they are working on the problem.

I just created a Discussion about problems with MATLAB Answers. https://www.mathworks.com/matlabcentral/discussions/general/877440-known-problems-in-matlab-answers . (It is currently waiting moderation.)

[John D'Errico]

Note that I had already created a discussion some weeks ago about the problems with Answers. No problem, as this just keeps the topic alive.

[Walter Roberson]

Looks like John's discussion is at https://www.mathworks.com/matlabcentral/discussions/general/875491-answers-not-displaying-symbolic-results
