Virtual link corresponds to:

<math> H_0= \begin{bmatrix} 1.0 & 0.0 & 0.0 & 0.0\\ 0.0 & 0.0 & -1.0 & 0.0\\ 0.0 & 1.0 & 0.0 & 0.0\\ 0.0 & 0.0 & 0.0 & 1.0 \end{bmatrix} </math> or if you prefer code:

 //H0 (1.0 0.0 0.0 0.0   0.0 0.0 -1.0 0.0  0.0 1.0 0.0 0.0   0.0 0.0 0.0 1.0)     // given per rows (Very precise MATLAB Matrix)
 Matrix H0(4,4);
 H0.zero();
 H0(0,0)=1.0;
 H0(1,2)=-1.0;
 H0(2,1)=1.0;
 H0(3,3)=1.0;
