Manually see YALMIP's conversion to Gurobi solver format

[Javier Jiménez Sicardo]

Hello,

I've been using Gurobi-Python bridge a couple months before and I'm currently using YALMIP as a Gurobi bridge, so I think I'm kind of knowledgeable with Gurobi's LP formats. Is there a way to check the optimizer output in Gurobi format so I can try and debug it myself? I haven't found anything in that regard on the documentations.

While my model is feasible, I'm not getting anything I could expect for a solution as control signal is constantly zero. Is something limiting sdpvar values from going negative? Gurobi implicitly limits continuous variable to >=0 in their GRB_CONTINUOUS definition unless expressedly told otherwise.

Thank you for your time!
