Well, my question concern more the crystal class than the Bravais
lattice actually.<br>
I was just wondering what the matrix of the cell parameters looks
like in a case of non triclinic cell.<br>
I'm wondering how the fact that a=b for instance is "translated" in
the matrix form of the cell parameters.<br>
One may also have less than six degree of freedom.<br>
Thank you,<br>
<br>
Eric.<br>
