model statistics

[Mostafa Nick]

Hi

How can I print statistics about the model by using Model.printStats(), in YALMIP using Gurobi solver?

Thank you in advance

1. Export the MATLAB data without solving anything
model = export(constraints,objective,

sdpsettings('solver','gurobi')

2. Export MATLAB model before solving (model saved to gurobidebug.mat)

ops = sdpsettings('solver','gurobi','savedebug',1)

solvesdp(constraints,objective,ops)
load gurobidebug

1 and 2 followed by
params = model.params;
params.ResultFile = 'mymodel.mps';
params.TimeLimit = 1;
gurobi(model, params);

3.Or tell gurobi to output model

ops = sdpsettings('gurobi.ResultFile','mymodel.mps');

solvesdp(constraints,objective,ops)

You might want to set time-limit parameter to 0 if you don't want gurobi to actually solve the problem
