1.2.46 `sm1.ecartd_syz'
-----------------------

sm1.ecartd_syz(A)
     :  It returns a syzygy of A by using  a tangent cone algorithm.
     h[0,1](D)-homogenization is used.   If the option rv="dp"
     (return_value="dp") is given,  the answer is returned in
     distributed polynomials.   The return value is in the format
     [s,[g,m,t]].   s is the generator of the syzygies, g is the
     Grobner basis,  m is the translation matrix from the generators to
     g.   t is the syzygy of g.
Example:

      input1
        F=[2*(1-x-y)*dx+1,2*(1-x-y)*dy+1]$
        FF=[F,"x,y",[[dx,1,dy,1],[x,-1,y,-1]]]$
        sm1.ecartd_syz(FF);
       input2
        F=[2*(1-x-y)*dx+h,2*(1-x-y)*dy+h]$
        FF=[F,"x,y",[[dx,1,dy,1],[x,-1,y,-1,dx,1,dy,1]],["noAutoHomogenize",1]]$
        sm1.ecartd_syz(FF);
