Hi there.

There is some floating bug in Thread-Seq.

Maple is crashing sometimes (not always, 50/50) after running the script below:

thread-seq_error.mw

What's going on?

Hi,all

I am new in Maple,when I execute the "InversePlot" command ,all functions were correct except for exp(x), error occurs as follows, can anyone tell me what mistake I took?

Tks in advance!

restart;
with(Student[Calculus1]);

InversePlot(exp(x), -1 .. 1);
Error, (in Student:-Calculus1:-InversePlot) module does not export `IsTrigProc`
 

Tks for all you guys. 

I have uninstall Maple and deleted the installed directory ,clear the register,reinstall Maple 2022, now all works well.

I think the problem is I installed Maple 2022 in the old directory of 2021for keeping my configuration,this caused much unexpected problem

> with(LinearAlgebra) :
> a:=<<.1,.2>|<.3,.4>>:
> ScalarMultiply(a,.1);

INTEL MKL ERROR: /home/jet08013/maple2022/bin.X86_64_LINUX/libmkl_gf_lp64.so: undefined symbol: mkl_blas_cdgmm_batch_strided.
Intel MKL FATAL ERROR: Cannot load libmkl_gf_lp64.so.
maple: fatal error, lost connection to kernel

This is EXTREMELY inconvenient.

Maple 2022:

It appears that one can use push_back() with an empty DEQueue(), but not push_front().

Since the queue is double-ended and empty, this doesn't make much sense to me. So should this be considered a "bug"?

I knew it can't be true that timelimit in Maple 2022 no longer hangs and it is only a matter of time before I find a case where it still hangs.

Here are examples. timelimit hangs. No error or anything, it just hangs. timelimit is just ignored. set the limit to 60 seconds  (CPU time), and waited for 20 minutes (real time) and nothing happend.

I hope in Maple 2023 this will be fixed. Could others confirm this? it only hangs when adding the method=_RETURNVERBOSE otherwise it does not hang.

This is a serious problem.

I change "how should maple handle the creation of new math engine?" to "Create new engine for each document". Then click on "Apply globally".  This is under Tools->Options->General

After I close Maple and start it again, I found it back to "Share one engine among all documents" ??

Why is that and how to make this permanent? 

Btw, the start Maple 2022 icon still says "Maple 2022 shared server". THis is in the start program menu. I complained about this in Maple 2021 but it is still not fixed.  https://www.mapleprimes.com/questions/231901-Why-Maple-2021-Only-Shows-shared-Server

I do not think this has anything to do with it. But who knows.

I noticed this when I started new worksheet and could not do anything in it because another worksheet was running something even though I made sure I had set the engine to start new one for each worksheet (this is the very first thing I do after I install Maple each time).

Any workaround to make the setting for the engine not change after closing Maple?
