title: Retrieve constraints matrix from Gurobi or MOI or JuMP in Julia
body: <p>I want to retrieve an LP model in matrix form from Gurobi. I am using package JuMP in Julia. I can print all the constraints using MathOptInterface but not in matrix form. I have no idea how to print the problem matrix from Gurobi. Could anyone help with this? Thanks very much in advance!</p>
  <p>Kind regards,</p>
