If by “real power flow” you mean the power transfer, then you can compute it from the lambda and the base and target power injections (loads, generations) according to equations (5.2)–(5.4) in the User’s Manual <http://www.pserc.cornell.edu/matpower/docs/MATPOWER-manual-5.1.pdf>. The lambdas after each predictor and corrector step, respectively, are returned in results.cpf.lam_p and results.cpf.lam_c.
If you mean the full power flow solution, then you’ll have to use the appropriate lambda to set set up the injections for the case, according to equations (5.2)–(5.4), and initialize the power flow with the corresponding bus voltages (from results.cpf.V_p or results.cpf.V_c) and run a simple power flow.
