Excuse me, my matlab version is R2020b, and mathrmatica is 13.0， MEvaluate,MGet works to simulate the matlab code in mathematica,. However, the MSet doesn't work to send mathematica variable to matlab

D:\Programfiles\matlab2020b\bin\win64 is added in system -> path regmatlabserver is also done with administrator rights

I have not noticed any issues with MSet on my computer. "doesn't work" is not a very precise statement. If you get different behaviour than what you expect, please show a minimal reproducible example and write the report this this form:

• This is what I did (complete instructions, starting with "launch Mathematica")
• This is what I expected to happen
• This happened instead

Additionally, post the output of MATLink`Developer`GetInfo[].

1 The first step, i obtain the mat file computed with matlab. The command 'MEvaluate' and 'Mget' works in this step

2. Then, with computing, e.g. test2=test1+1, it doesn't display in the work space of matlab

MATLink does not connect to an already running MATLAB. It launches its own private version of MATLAB in the background. Use MEvaluate["who"] to see the workspace.

On Windows only, there is a way to connect to an already running MATLAB, but I can't consider this supported functionality until we get the time to rewrite MATLink to use more recently introduced APIs. Personally I won't have time for that in the near future. The steps to connect to a running MATLAB are here, but again, consider this unsupported:

Thanks a lot. Matlink is very good. I like it.
