%CVodeInitB allocates and initializes backward memory for CVODES.
%
% Usage: IDXB = CVodeInitB ( FCTB, LMMB, NLSB, TB0, YB0 [, OPTIONSB] )
%
% FCTB is a function defining the adjoint ODE right-hand side.
% This function must return a vector containing the current
% value of the adjoint ODE righ-hand side.
% LMMB is the Linear Multistep Method ('Adams' or 'BDF')
% NLSB is the type of nonlinear solver used ('Functional' or 'Newton')
% TB0 is the final value of t.
% YB0 is the final condition vector yB(tB0).
% OPTIONSB is an (optional) set of integration options, created with
% the CVodeSetOptions function.
%
% CVodeInitB returns the index IDXB associated with this backward
% problem. This index must be passed as an argument to any subsequent
% functions related to this backward problem.
