yalmip and gurobi jointly solve the problem, but Matlab tells me that it is an infeasible model.
I want to use IIS to check the infeasible constraints,
but I can't use it successfully.
Do I have to write the model separately to use IIS?
Since I'm a newbie in gurobi,
I would like to ask if I can call a heuristic in gurobi
to solve a two-stage stochastic programming problem (MILP problem)?

  Hi Chen,

  If you can write the model to an MPS or LP file using YALPMIP, then you can easily compute the IIS to see the Gurobi command line:

  gurobi_cl ResultFile=myiis.ilp yalmipmodel.lp

  Otherwise, you can also follow their guide: Debugging infeasible models.

  Cheers, 
  David
