Workspace variable statistics don't work

Hi,

I have just upgraded to R2017b and I've noticed that the columns in the Workspace panel don't display anything (except Value, Range, Size, Bytes, Class). Is there a setting that I should change so that I can see the statistics for my variables?

Thanks, Panos

You mean like showing the min and max values? Have you looked in the setting? I don't think I have seen it since something like 2014/2015, but then I didn't really use that feature.

[Panos]

Yes exactly. The functions themselves work fine when I call them but I can't see them on the workspace columns.

[Rik]

I just tried it out, and it indeed doesn't show any value. Odd. Only size, bytes and class (and value and name) actually show any values.

Maybe someone with R2017a can confirm this is new?

But it cannot be found from the Workspace actions on the top of workspace?

[Rik]

As you can see in Panos' screenshot, the column is already enabled, it is just empty.

[Kian Azami]

Yes Rik, so it is something related to the new version. Maybe if you check the Workspace setting in the 'Preferences' at the Home tab, you find something about this issue.

[Panos]

@Kian I've already done that but there is no relevant field for my problem. Do you have the same problem? It's not clear from the image you posted.

[Rik]

In the preferences you can modify the maximum size of variables analyzed and whether or not NaNs should be considered in calculation. Changing either or both does not result in the statistics being calculated for a=1:10;, so clearly there is something wrong here.

How can we notify Matlab staff about this issue?

Hello,

This bug has been fixed in this patch: https://www.mathworks.com/support/bugreports/1627216

[Adam]

I'm not seeing a download link for a patch at that link. Am I just being blind?

I believe what Chandani meant is that the bug has been captured in this Bug Report entry.

According to the Bug Reports FAQ you can add this bug to your watch list by clicking on the check mark next to it. Once you've added the bug to your watch list "You can then set your e-mail preferences for the Watch Bugs list to get e-mail notifications when updates are available."

I have not tried this myself but I believe the bug report gets updated, and users watching it are notified, when a release comes out in which the bug is fixed. [It may also be updated when the developers responsible for that issue have additional information, workarounds, patches, etc.]

[Adam]

Hmm, I can't click the check mark, or rather it does nothing when I do. Seems to be the case for all bugs too. Maybe it's a bug :)

[Adam]

Ah, ok, when I 'zoomed out' to the wider bugs list that included it the check mark does work.
