Try, s2[1] or op(s2)[1]

@acer ah.  ok thanks.

I guess padding without the ImageTools package I could just pad the Matrix like this.

a := Matrix(16, 16, rand(0. .. 1.0)):
b := Matrix(18, 18, 0):
b[2 .. 17, 2 .. 17] := a:
b;

@acer Thanks, that's a good way,

Slightly forgot about the Preview command which displays axes and will at least give you a rough idea.

@C_R  You got it, image outputs of imagetools routines or imports of images.

I'd also like to say not all commands work the same across the entire family of Maple or user created packages.  A different definition may be used for the same command within another package.  One may have carefully crafted a Maple document only to find out it breaks when loading a stray package on some brilliant new idea they might have just thought of.  Similarily the sequence structure may be viewed differently when other packages are loaded. 

I just believe it common practice to use some type of bracket in a sequence, be it a list, set, vector etc... not always a requirement but probably not a bad habit to get in to.   Especially as Eric pointed out, if using them for any type of mathematical operation. 

@QM There is a case# assigned to my request.  A replied email to the support request mentioned they would do their best to get back to me within one business day.  I suspect they are putting contingency plans in place to update the website overnight or worst case over the weekend. 

I find the online help useful in discovering what's new in the latest release.  Also when I'm at work or don't have access to maple I can still use the online help.

@QM Oh Sign in, ok.  Actually I forgot about that, probably because I never use it - and probably why I've never noticed it missing.  I closed and re-opened Maple a few times on 2021.1 and 2022.0 and so far haven't had an occurrence of the sign in disappearing

@QM It is quite surprising. 

 I have contacted Maplesoft and made them aware of the issue.

Looks like it was overlooked.  But yes it would mean the online help pages are only up to date to Maple 2021, that means all of 2022 was missed!  The other possibility is that it didn't get linked properly.  I find it hard to believe that the online help pages could have gone through all of 2022 without being updated. 

Happy to say the issue is fixed or doesn't occurr in Maple 2023.

@QM What is sig in?  I can't see it, can you point it out?  Otherwise it looks perfectly normal to me.

The fault also exists in Maple 2021.  I can't verify if it exists in Maple 2023.

@acer Thanks for your solution variant.

Actually the font size or font width doens't matter.  Only concerned about the number of characters within the output.  It could contain non-ASCII characters, and the whitespace need not be removed. 

The trailing / I thought was what maple used as a continuation of an answer.  Actually sorry I meant the forward slash, mistake on my use.

@Carl Love I didn't intend to remove the spaces, I actually just forgot they were included in the output.

As for the output, it's mainly for text solutions, didn't have intention for plots.
