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?

Whay the command:  123! + 1 takes significantly more time than 123! only??? Moreover time(123!+1) and time(123!) are very similar and fast.

I am using Worksheet GUI.

I need to solve general linear programming problem with multi-precision support. What are my options with Maple 2020?
