%IDAGetStatsB returns run statistics for the backward IDAS solver.
%
% Usage: STATS = IDAGetStatsB(IDXB)
%
% IDXB is the index of the backward problem, returned by IDAInitB.
%
%Fields in the structure STATS
%
%o nst - number of integration steps
%o nre - number of residual function evaluations
%o nsetups - number of linear solver setup calls
%o netf - number of error test failures
%o nni - number of nonlinear solver iterations
%o ncfn - number of convergence test failures
%o qlast - last method order used
%o qcur - current method order
%o h0used - actual initial step size used
