(1.3)  :

$\displaystyle \left\{ \begin{array}{c} x = m_{11}x'+m_{12}y'+m_{13}z'+c_1\\ ... ...+m_{23}z'+c_2\\ z = m_{31}x'+m_{32}y'+m_{33}z'+c_3\\ \end{array} \right.$







(1.4)  :

$\displaystyle \left( \begin{array}{c} 1\\ x\\ y\\ z\\ \end{array} \rig... ...cal{M}} \left( \begin{array}{c} 1\\ x'\\ y'\\ z'\\ \end{array} \right)$







(1.6)  :

$\displaystyle \left( \begin{array}{cccc} 1 & x' & y' & z'\\ \end{array} \... ... \left( \begin{array}{c} 1 \\ x' \\ y' \\ z'\\ \end{array} \right) = 0$







(1.7)  :

$\displaystyle \mathcal{B}\: = \hspace{2mm} ^t\widetilde{\mathcal{M}} \hspace{1mm} \mathcal{A} \hspace{1mm} \widetilde{\mathcal{M}}.$







(1.8)  :

$\displaystyle \mathcal{B}_0 = \hspace{2mm} ^t\mathcal{M} \hspace{1mm} \mathcal{A}_0 \hspace{1mm} \mathcal{M}$
