you may want to change that to

"include BEKK.gfn"

and check for functions beginning with "Get_": those have now a different name.

Jack, do I understand correctly that there was for example a "Get_Loglik" function in MGARCH which has become "BEKK_GetLoglik" in the new BEKK package? (And similar for the new BEKK_GetResids,  BEKK_GetVariance, and BEKK_GetCovariance.)

thanks
