The Physics Update package install or upgrade via cloud is not working now. See the error code:

Same problem on Maple 2021 and Maple 2022 (linux and windows version).

Any help?

I am using Maple 2021.2 on Ubuntu Linux 20.04 LTS. Sometimes the Maple after start does not show Sig in part of top Maple desktop panel. So I need to restart Maple and 2nd or 3rd start is mostly OK. After that is the situation for some time good.

See attached snapshot... Any idea what is wrong?

Latest updates of Physics package (problem start with version cca 1020) is not announced at Maple cloud user window (see attacehd snapshot). The same problem occur on Windows and Linux platform!

 

When I want to generate matlab code of the following symbolic expression I got very strange result:

with(CodeGeneration);
Matlab(Sum(a(i), i = 1 .. N));
Warning, the function names {Sum, a} are not recognized in the target language
Warning, precedence for Range unspecified
Warning, cannot translate range
cg = Sum(a(i), i == (1..N));

 

Problem:Sum(a(i), i == (1..N));

 

Right matlab code should look like:

cg = sum(a);

Where can I found compete list of supported matlab built-in function? Is there any possibility how to get proper matlab code?

Is there any way how to convert more complex symbilic expressions to the Matlab???

Is possible to operate Grid Computing Toolbox together with Maple on one local multicore machine?

If yes, what is the proper instalation/configuration procedure on Windows or Linux?
