Hello @nm ,

This is a good question and we are looking into it

Update: this was fixed in Maple 2023.0

Hello,

Is this expected when considering that there is a unique command that matches "pie" but there are several help articles?

Hello @tomleslie,

This problem has been fixed in the Maple 2021.1 update. Please let us know if you are still encountering any issues with this. 

Hello @Anthrazit ,

Thank you for bringing this to our attention.

It appears the limitation isn't isolated to references to another sheet, and that it can be avoided when cells are copied and pasted as opposed to referenced.

Thank you for engaging the Primes community @lmordecai , and thank you for the discussion @Carl Love .

A support case has also been opened and we are looking into it. 

In this instance, the error appears to be caused by a Matrix calling sequence passed more than 24 lists, possibly by just omitting a set of square brackets meant to denote a list of lists. 

i.e.

A:=Matrix(25,1, [ [list1] , [list2] , [list3] , ..., [list25] ]);

  is accepted, but

B:=Matrix(25,1, [list1] , [list2] , [list3]...,[list25] );

generates Error, (in Matrix) too many patterns for typematch

For now, the solution is to just use a list of lists calling sequence fto create the Matrix.

We'll separately determine if improvements need to be made to the product and/or documentation to handle this case.

Thanks for the discussion everyone.

Following up on @tomleslie 's report, our developers think that the real solver will be made more robust to prevent this kind of error in future versions of Maple.

For now, they suggest that,

an easy solution here is to avoid the real solver (don't set the environment variable, or give the 'real' option to solve). complex techniques easily find all 5 real solutions. In fact, fsolve does as well, and is actually a better choice here given all the floating point values in the input.

Thanks for bringing it to our attention @Anthrazit ,

You can see that even if you modify the attachement code to take a string as defined in the worksheet it works. 

The problem appears to be entering special characters into the code editor window. 

We've logged a request to consider enhancing in future versions of Maple.

We hope the workarounds suffice in the meantime.

Hello 

Thank you for bringing this issue to our attention. After investigation the root cause of this issue has been identified and addressed in a patch release that we are targeting to deploy as an automatic update from within Maple in the next week.

If you would like to obtain the fix for this issue immediately we recommend downloading a new copy of the full Maple installer and performing a reinstall of Maple. You can obtain a copy of this new version by downloading Maple again using the download link sent in your order confirmation email. If you no longer have or can not find your download link you can visit our download website: https://www.maplesoft.com/download/, and supply your purchase code to get a fresh download link.

If you require any additional support or have questions you can contact Support by submitting a support request at: https://www.maplesoft.com/contact/webforms/support.aspx, and we would be happy to assist you further.

Maplesoft Technical Support

Other users have had a similar problem lately. It seems many also have BullGuard Security installed on their machines, and white-listing Maple has fixed the problem.

BullGuard has instructions for this process on its website:

https://www.bullguard.com/support/product-guides/internet-security/guides-for-current-version/firewall/application-rules-guide.aspx

For BullGuard, rules are listed by application, and you would want the policy to be "Allow" and direction to be "In+Out".

Some security software require specific files or folders, though. You can try to white-list the entire

C:\Program Files\Maple 2018\

folder (we're assuming 64-bit Windows and Maple 2018 here), but to include only specific files, you would typically want to white-list these:

C:\Program Files\Maple 2018\bin.X86_64_WINDOWS\cmaple.exe
C:\Program Files\Maple 2018\bin.X86_64_WINDOWS\maplelauncher.exe
C:\Program Files\Maple 2018\bin.X86_64_WINDOWS\maplew.exe
C:\Program Files\Maple 2018\bin.X86_64_WINDOWS\mserver.exe
C:\Program Files\Maple 2018\jre\bin\javaw.exe

The last one in particular, javaw.exe, is what is specifically added to Windows Firewall and others' exceptions when Maple is launched for the first time.

I recommend you contact Maplesoft Customer Service at custservice@maplesoft.com. Depending on the situation, they may issue a new purchase code different than those above (which can no longer be used to activate Maple).
