Matlab crashes with Gurobi

Hi to everyone, any help would be highly appreciated.

I am using Gurobi 9.1.2 and I have tested the following in both Matlab versions 2019b and 2020a in different environments.

I have also tested the following by using Primal and Dual Simplex algorithms. The crash happens only with Primal Simplex or the default method (-1).

I am able to solve small LPs, for instance with LPs with 200 variables and 5 constraints, however Matlab crashes when I am trying bigger LPs (1000 variables and 6 constraints).

I provide below the crash, as far as I can tell, it has to do with MEX and memory issues.

This error was detected while a MEX-file was running. If the MEX-file
is not an official MathWorks function, please examine its source code
for errors. Please consult the External Interfaces Guide for information
on debugging MEX-files.

 

Thank you in advance for any assist!

    Hi Greg,

    Gurobi 9.5 was recently released. Included in this release is a fix for the bug you observed. Using Gurobi 9.5, your model runs as expected with the default Method=-1 and Method=0.

    We hope this fix works well for you. Thank you for reporting this bug and please let us know if you find any other issues in the future.

    Best regards,

    Maliheh
