Is it correct that there is no MATLAB interface for 20.1.0.0? If so, are there any plans to add it at a later date, or is 12.10 the end of the line for MATLAB interface for CPLEX?

Hi

Is it correct that there is no MATLAB interface for 20.1.0.0?

==> Yes

If so, are there any plans to add it at a later date, or is 12.10 the end of the line for MATLAB interface for CPLEX?

==> Do not hesitate to log a wish in Aha to have this back : https://ibm-data-and-ai.ideas.aha.io/?project=CPLEX

(Database connectivity in OPL was removed in CPLEX 12.7 and is back in 20.1 thanks to many Aha votes)

In the meantime, many options:

•  keep using CPLEX 12.10
• call OPL from Matlab :

                 https://github.com/AlexFleischerParis/howtowithopl/blob/master/callfrommatlab.M

                 https://github.com/mjbays/MATLAB-OPL-Interface

• export MPS from Matlab with https://www.mathworks.com/matlabcentral/fileexchange/19618-mps-format-exporting-tool and then call CPLEX
• use a Matlab connector like TOMOPT https://tomopt.com/

Or you can also

• use the MATLAB connector from CPLEX 12.10 and export the mps file with

The parameter ExportModel (or exportmodel) takes a file name as an argument.
The default is the empty string (""). For example, opt =
cplexoptimset('exportmodel', 'myModel.lp'); can be used to set the name of
the exported model.

then call CPLEX from Matlab through a command line call

• keep using CPLEX 12.10
  • Will this work with renewal of (academic) licenses? e.g. If a person renews an optimisation studio licence, can they elect to download CPLEX 12.10 and keep using that? For how long?
• call OPL from Matlab :

With a matlab-OPL-cplex interface, is there any way to avoid writing and reading flat files? There would be a major performance drop if not.

• export MPS from Matlab with https://www.mathworks.com/matlabcentral/fileexchange/19618-mps-format-exporting-tool and then call CPLEX

• use a Matlab connector like TOMOPT https://tomopt.com/

Tomlab's matlab interface is excellent, however there do not seem to be free academic licenses for it that last longer than a few weeks.
