%
% The function GLOCFUNB must be defined either as
% FUNCTION [GLOCB, FLAG] = GLOCFUNB(T,YY,YP,YYB,YPB)
% or as
% FUNCTION [GLOCB, FLAG, NEW_DATA] = GLOCFUNB(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 GLOCB
% corresponding to an approximation to fB(t,yy,yp,yyB,ypB).
%
% The function GLOCFUNB must set FLAG=0 if successful, FLAG<0 if an
% unrecoverable failure occurred, or FLAG>0 if a recoverable error
% occurred.
%
% See also IDAGcommFnB, IDAGlocalFn, IDASetOptions
%
% NOTE: GLOCFUN and GLOCFUNB are specified through the GlocalFn property
% in IDASetOptions and are used only if the property PrecModule
% is set to 'BBDPre'.
