Cannot make Matlink 1.1 work with Matlab2021b/Mathematica 13.1

[Arjay-El]

I set up MATLink in the stated directory. SystemOpen@FileNameJoin[{$UserBaseDirectory, "Applications"}] -> I placed directory MATLink there.

Cell code Input: Needs["MATLink`"] OpenMATLAB[] MEvaluate["mat = magic(4)"]

Output: $Failed ...OpenMATLAB: Could not open a connection to MATLAB ... MEvaluate: The MATLAB workspace is already closed

The logfile states; Mon 26 Dec 2022 20:46:37 fatal Could not open a connection to MATLAB.
Mon 26 Dec 2022 20:46:37 warning The MATLAB workspace is already closed. Mon 26 Dec 2022 20:51:40 fatal Could not open a connection to MATLAB.
Mon 26 Dec 2022 20:51:40 warning The MATLAB workspace is already closed. Mon 26 Dec 2022 20:55:31 fatal Could not open a connection to MATLAB.
Mon 26 Dec 2022 20:55:31 warning The MATLAB workspace is already closed.

I have matlab and mathematica pathed properly.

In Mathematica, it gives me autocompletion for OpenMATLAB so its seems to have the app loaded.

In matlab, executing [reg,msg]= regmatlabserver gives

[s,msg]=regmatlabserver s = 0 msg = 0×0 empty char array

Is there a way to troubleshoot this?

Please post the output of

Needs["MATLink`"]
MATLink`GetInfo[]

[Arjay-El]

Copied code into cell and executed it. I see Math1.png

Added a space between MATLink` and GetInfo[]. I see Math2.png.

I'm sorry, I meant

I also have the same trouble, with same version Matlab and Mathematica.

I had to make sure all the Matlink folders had a path to them, then gave all the files admin permission. That made it work. It seems to be a permission issue. I did not go back and take the admin status off all the files one by one to see which file was causing the problem. Its running and I have left it as is.
