- ``Norm_sqr(v)`` for ``v`` a vector or a matrix gives the square of the
euclidean norm of a vector or of the |Frobenius| norm of a matrix. For a vector
this is equivalent to ``v.v`` and for a matrix to ``m:m``.
+ - ``Normalized(v)`` for ``v`` a vector or a matrix gives ``v`` divided by
its euclidean (for vectors) or frobenius (for matrices) norm.

- ``Det(m)`` gives the determinant of a square matrix ``m``.
- ``Inv(m)`` gives the inverse of a square matrix ``m``. The second
derivative is not available since it is an order 6 tensor. This means that
``Inv(m)`` cannot be used in the description of a potential energy.
+
+ - ``expm(m)`` gives the exponential of a square matrix ``m``.
+
+ - ``Logm(m)`` gives the logarithm of a square matrix ``m``.
- ``Matrix_I2(m)`` gives the second invariants of a square matrix ``m``
which is defined by ``(sqr(Trace(m)) - Trace(m*m))/2``.
