PURPOSE ^

CPF_VLIM_EVENT Event function to detect bus voltage limit violations

SYNOPSIS ^

function ef = cpf_vlim_event(cb_data, cx)

DESCRIPTION ^

CPF_VLIM_EVENT  Event function to detect bus voltage limit violations
   EF = CPF_VLIM_EVENT(CB_DATA, CX)

   CPF event function to detect bus voltage limits violations,
   i.e. Vm <= Vmin or Vm >= Vmax.

   Inputs:
       CB_DATA : struct of data for callback functions
       CX : struct containing info about current point (continuation soln)

   Outputs:
       EF : event function value
