function [Jul1,Jul2]=TCB2TDB(Jul1,Jul2)
%%TCB2TDB Convert from  barycentric coordinate time (TCB) to barycentric
%         dynamical time (TDB), both represented as two-part Julian dates.
%
%INPUTS: Jul1, Jul2 Two parts of a Julian date given in TCB. The units of
%                   the date are days. The full date is the sum of both
%                   terms. The date is broken into two parts to provide
%                   more bits of precision. It does not matter how the
%                   date is split.
%
%OUTPUTS: Jul1, Jul2 The time as a Julian date in TDB.
%
%This is a mex wrapper for the function iauTcbtdb in the International
%Astronomical Union's (IAU) Standard's of Fundamental Astronomy library.
%
%The algorithm can be compiled for use in Matlab  using the 
%CompileCLibraries function.
%
%The algorithm is run in Matlab using the command format
%[Jul1,Jul2]=TCB2TDB(Jul1,Jul2);
%
%Many temporal coordinate systems standards are compared in [1].
