%
% The function DJACFUNB must be defined either as
% FUNCTION [JB, FLAG] = DJACFUNB(T, YY, YP, YYB, YPB, RRB, CJB)
% or as
% FUNCTION [JB,FLAG,NEW_DATA] = DJACFUNB(T,YY,YP,YYB,YPB,RRB,CJB,DATA)
% depending on whether a user data structure DATA was specified in
% IDAInit. In either case, it must return the matrix JB, the
% Jacobian (dfB/dyyB + cjb*dfB/dypB). The input argument RRB contains
% the current value of f(t,yy,yp,yyB,ypB).
%
% The function DJACFUNB must set FLAG=0 if successful, FLAG<0 if an
% unrecoverable failure occurred, or FLAG>0 if a recoverable error
% occurred.
%
% See also IDADenseJacFn, IDASetOptions
%
% NOTE: DJACFUNB is specified through the property JacobianFn to
% IDASetOptions and is used only if the property LinearSolver was
% set to 'Dense'.
