%
% The function JTVFUNB must be defined either as
% FUNCTION [JVB, FLAG] = JTVFUNB(T,Y,YB,FYB,VB)
% or as
% FUNCTION [JVB, FLAG, NEW_DATA] = JTVFUNB(T,Y,YB,FYB,VB,DATA)
% depending on whether a user data structure DATA was specified in
% CVodeInit. In either case, it must return the vector JVB, the
% product of the Jacobian of fB(t,y,yB) with respect to yB and a vector
% vB. The input argument FYB contains the current value of f(t,y,yB).
%
% The function JTVFUNB must set FLAG=0 if successful, or FLAG~=0 if
% a failure occurred.
%
% See also CVodeSetOptions
%
% NOTE: JTVFUNB is specified through the property JacobianFn to
% CVodeSetOptions and is used only if the property LinearSolver
% was set to 'GMRES', 'BiCGStab', or 'TFQMR'.
