IBM Cplex Version 12.8

I was looking at this post because I get the error due to not having version 12.8 installed ( https://www.mathworks.com/matlabcentral/answers/354479-why-does-matlab-crash-when-i-run-code-using-ibm-s-matlab-cplex-connector?s_cid=pl_crsh_an )

I was looking on the IBM site and that particular version is unpublished. Is there a repository that it was moved to or will everything in the project that I'm working on need to update? My current matlab installation is 2023a and the current installation of CPLEX is 12.9, but its throwing errors left and right with notes saying I need 12.8. Something it says is run the generateMexFastFVA() on the command line but this trips a crash report that links to the above link. Thank you

Hi @Alexander

I understand that you are trying to use IBM CPLEX version 12.9 with MATLAB R2023a. However, they are not compatible. The versions of CPLEX with latest compatible version of MATLAB are:

• IBM ILOG CPLEX Optimization Studio Version 22.1.1.0 – does not support MATLAB
• IBM ILOG CPLEX Optimization Studio Version 22.1.0.0 – does not support MATLAB
• IBM ILOG CPLEX Optimization Studio Version 20.1.0.0 – does not support MATLAB
• IBM ILOG CPLEX Optimization Studio Version 12.10.0.0 – MATLAB R2019b and future fix packs
• IBM ILOG CPLEX Optimization Studio Version 12.9.0.0 – MATLAB R2018b and future fix packs

This information is available at https://www.ibm.com/software/reports/compatibility/clarity/prereqsForProduct.html by entering “IBM ILOG CPLEX Optimization Studio” in the field “Full or partial product name”. Select the version 22.1.1.0/22.1.0.0/20.1.0.0/12.10.0.0/12.9.0.0 in the version field and look for “MathWorks MATLAB” under Development Tools in the generated compatibility report.

Since MATLAB R2023a is not supported by CPLEX, you can use an older release of MATLAB. To do so, log in to your MathWorks account and navigate to the Downloads page, where you can then select the relevant release to download.

I hope this helps!

Does 12.8 have any relevance?

The relevance of CPLEX version here is the range of MATLAB versions supported. For version 12.9.0.0 the supported versions are MATLAB R2015b 8.6 to R2018b. For version 12.10.0.0 the supported versions are MATLAB R2017a 9.2 to R2019b.
