I am trying to set up a MATlink using the instructions given here. I get an error while running the following commands

Needs["MATLink`"]
OpenMATLAB[]

Error:

The procedure entry point gzdirect could not be located in the dynamic
link library C:\Program Files\MATLAB\R2019b\bin\win64\libxml2.dll

Could someone suggest how this can be resolved?

EDIT: As suggested in the comment, I am also providing the output of

MATLinkDeveloperGetInfo[]

  • $\begingroup$ As mentioned in the troubleshooting notes, it is critical that you include the output of MATLink`Developer`GetInfo[] , otherwise we cannot guess at the cause of the problem. When you say "the instructions given here", did you forget to include a link to the instructions? $\endgroup$

  • $\begingroup$ Please evaluate SystemOpen@FileNameJoin[{DirectoryName@FindFile["MATLink`"], "..","Engine", "bin", "Windows64"}]. It will open a directory containing mengine.exe. Run this program manually (double-click it). What happens? You should get a small window asking to "Create link" with OK and Cancel buttons (you can just cancel). $\endgroup$

  • $\begingroup$ @Szabolcs yes, I get the small window with "Create link". Clicked cancel . Then I get another small window, clicked cancel for this one too. How should I proceed next? Please let me know $\endgroup$

The cause is that the "../libxml2.dll" file in other directory is used instead of MATLAB installation directory. The solution is adding or moving the MATLAB installation directory at the start of the system path. As for me, here is the start of my system path. After adding the path, please restart the Mathematica and run the commands again.
