    Hi Kudria,

    There is no dedicated C++ method to return the coefficient matrix in a compressed format. The APIs for C++, Java, and C# are object oriented and you would have to iterate over either Column or Constraint object and construct a CSR format on your own. However, in your case since you are using C++, you can use the C function GRBgetconstrs(), which will do the job for you.

    Best regards,
