I want to retrieve the shadow prices of a small ILP, so I tried using pi but the same error keeps coming. What to do?

c = [2; 1];

n=2;

A=[3 2;3 1;1 2];

b=[80;50;60];

l=[0 0];

 

model.obj=c;

model.A= sparse(A);

model.rhs=b;

model.vtype=repmat('I',n,1);

model.lb=l;

model.modelsense='max';

 

results = gurobi(model);

dual=results.pi;

disp(dual)

  Please note that the Pi attribute is only available for linear programs. We discuss this in the Knowledge Base article How do I retrieve the (dual) Pi value for a MIP problem?
