%
% The function DAEFUNB must be defined either as
% FUNCTION [RB, FLAG] = DAEFUNB(T, YY, YP, YYB, YPB)
% or as
% FUNCTION [RB, FLAG, NEW_DATA] = DAEFUNB(T, YY, YP, YYB, YPB, DATA)
% depending on whether a user data structure DATA was specified in
% IDAInit. In either case, it must return the vector RB
% corresponding to fB(t,yy,yp,yyB,ypB).
%
% The function DAEFUNB must set FLAG=0 if successful, FLAG<0 if an
% unrecoverable failure occurred, or FLAG>0 if a recoverable error
% occurred.
