I have attempted to solve a MIP problem in MATLAB CPLEX API. How can I get duals from MATLAB directly?(in need of correlated codes)。
I am a rookie in CPLEX. Can anybody help me?

Hello,

MIP don't have duals. But you could fix the integer values to their current values and then solve as a LP to get duals, if that's fine for your problem. To do that, you need to change the problem type to 'fixed_milp', then solve as LP and then get the duals.
