How to recover the decision boundary from LIBSVM?

I am trying to recover the decision boundary from the model resulting from svmtrain of LIBSVM in Octave. The output of the model is shown in the following, I highlighted the parameters I think correspond to the decision boundary equation:

This is the decision boundary equation:

How do I recover the decision boundary u using the equation and the model parameters above? I'd like to do this without calling svmpredict.

Thanks.
