Hi,

How should I do to use Gurobi from Matlab when we only have the Cloud License?

This information

https://www.gurobi.com/documentation/9.0/quickstart_windows/matlab_setting_up_grb_for_.html

seems to only be for the local solver of Gurobi and Matlab.

/Lars

  Hi Lars,

  The setup is the same. You just need to specify your Cloud credentials when solving a model.

  1. In the Cloud Manager interface, navigate to Settings->API Keys. If you do not have an API key for your license, create one. Note the Access ID and Secret Key.
  2. In MATLAB, create an env \( \texttt{struct} \), populating the \( \texttt{accessid} \) and \( \texttt{secretkey} \) fields: \( \texttt{env = struct('accessid', '<access ID here>', 'secretkey', '<secret key here>');}. \) You can optionally specify a \( \texttt{pool} \) field.
  3. Pass this \( \texttt{env} \) \( \texttt{struct} \) to the gurobi() function: \( \texttt{result = gurobi(model, params, env);} \).

  Thanks,

  Eli

  Hi Eli,

  To start with, if following the instructions in https://www.gurobi.com/documentation/9.0/quickstart_windows/matlab_setting_up_grb_for_.html, there is no "gurobi_setup.m" file in the "C:\gurobi_server902" directory.

  Hi Lars,

  The \( \texttt{gurobi_server902} \) package is for Gurobi Remote Services, which you don't need with a Cloud license. You should download the Gurobi Optimizer package from the Gurobi website, which installs to \(\texttt{C:\gurobi902}\). The \( \texttt{gurobi_setup.m} \) file can then be found in \( \texttt{C:\gurobi902\win64\matlab} \).

  Thanks,

  Eli

  Ah, so it is the same package to install as if you have a local license? https://packages.gurobi.com/9.0/Gurobi-9.0.2-win64.msi ?

  Hi Lars,

  Yes, that's correct.
