Reference to non-existent field 'computeIIS'.

Hi, Im trying to code a big Mixed Integer Problem by calling Gurobi from Matlab. It seems that the problem is infeasible, so I tried to use computeIIS as it is shown here:
but I get the following error when I run my code:
Reference to non-existent field 'computeIIS'.
The Function that calls Gurobi in Matlab is as follows:
function mip1_P_F()
load('mip1_P.mat');
model.A = sparse(A);
model.obj = Obj;
model.rhs = B ;
model.sense = Signs;
model.lb = LB;
model.ub = UB;
model.vtype = VT;
model.modelsense = 'max';
model.varnames = names;
gurobi_write(model, 'mip1_P.lp');
params.outputflag = 0;
result = gurobi(model, params);
disp(result);
model.computeIIS();
for v=1:length(names)
fprintf('%s %d\n', names{v}, result.x(v));
end
fprintf('Obj: %e\n', result.objval);
end
Im not sure what is wrong, Ill appreciate your help!!!

Does model exist within that mat file that you are loading ? You should avoid poofing variables into existence as MATLAB is permitted to assume at parse time that the structure assignment to model have nothing to do with the load.
