%IDAQuadInitB allocates and initializes memory for backward quadrature integration.
%
% Usage: IDAQuadInitB ( IDXB, QBFUN, YQB0 [, OPTIONS ] )
%
% IDXB is the index of the backward problem, returned by
% IDAInitB.
% QBFUN is a function defining the righ-hand sides of the
% backward ODEs yQB' = fQB(t,y,yB).
% YQB0 is the final conditions vector yQB(tB0).
% OPTIONS is an (optional) set of QUAD options, created with
% the IDASetQuadOptions function.
