Hi all,

In Matlab/Yalmip, we can using `export`, we can get the coefficient matrix and several “standard form” based on certain solver. For example, if we use Gurobi, we can use `export` to get `A`, `rhs`, `sense`, `vtype`, `obj`…

I would like to know if there are similar functions in JuMP?

I think JuMP is also convert various constraints entered by users into a form acceptable to a specific solver.

Thanks a lot!

Unfortunately, there isn’t.

There is a work-in-progress, but it isn’t finished yet: [GitHub - jump-dev/MatrixOptInterface.jl: An interface to pass matrix form problems](https://github.com/jump-dev/MatrixOptInterface.jl)
