@Fereydoon_Shekofte 

You're welcome! I'm glad to hear you found it interesting. I hope to find some time for more fun stuff.

@Joe Riel 

on a different Windows 10 PC after system restart:

• After 5 minutes of waiting I started Maple 2022 and Maple 2021 which also tried to open the start page.
• After 10 minutes I killer all Maple instaces
• Starting Maple 2023: the same issue. I left to grab something to eat. When I came back after 25 min the start was opend.
• I disabled the start page and enabled it again. Now it seems to start normally. I will keep an eye on it on this machine as well.

@Carl Love 

Only for information:

I read that it might be realated to the graphic card help(plot3d,gldriver). Since my oberservation were on ATI I tested it the same input on NVIDA under 4k.

Its not so tiny but still too small IMO.

@delvin 

That's a new question.

Are you aware that you are trying to plot a univariate, complex valued function as a surface plot?

For a surfaceplot you need a bivariate real valued function.

I have stopped using Matlab a long time ago and, as I have said above, I do not have an installtion running. I am afraid I can't help you any further. Maybe this community can

@Joe Riel 

I restored the start page and restarted. Starts fine for the moment. I will leave the start page on and post here when it happens again.

Before further investigation: Could you have a look if Maple 2023 output meets your expectations?

@delvin 

You can plot less lines (see linespace in the code above) or make the lines thinner (surface properties).

For that, have a look at the online documentation:

@acer Thank you.

It's a bit confusing that the complete integral of the first kind got its own symbol but not the complete integral of the second kind.

It seems that it is widely used in this way.

What do you mean by guiding?

What do you mean by "3D chart"? `Do you mean the output of plot3d?

@ecterrab 

 Selecting with the mouse and scrolling takes too long, but this way it works acceptably and(!!!) preserves the output:

S1: place the cursor where to stop

S2: Select all the above with Crtl+Shift+Home (on Windows)

S3: from the menu: Evaluate -> Selection

Thank you

Before I read your post I was quite happy with what I saw on the screen.

Now I see these "absurdly" long negations everywhere. Here a sample from a text passage

I clearly am in favour of a shorter version.

@Carl Love 

That's a good workaround!

Since 2d is not affected by tiny rendering (below: left 4k right 2k) and the rendering changes without Maples GUI and kernel dooing anything, I think that the issue is more openGL related.

Thats how the the output looks like when I change back to 4k (without execution of any commands. i.e. it is the same plot as above):

(A while ago I contacted support with that issue but they could not reproduce it because they had no 4k monitors to test.)

@Carl Love 

My example was misleading. Older Maple version did not allow to use implicitplot3d without ranges so I put something that did not match the OPs screenshot.

I can exactly reproduce the tiny fonds and how it looks differently if I change to 2k (with Maple 2023)

@acer 

Thank you. I looked at the wrong spot for the Airy question. For "_M" I can't find anything.
