Tenseur_sym Lorene::lie_derive | ( | const Tenseur_sym & | t, |
const Tenseur & | x, | ||
const Metrique * | met = 0x0 |
||
) |
Lie Derivative of t
with respect to x
.
If no other argument is given, it uses partial derivatives with respect to cartesian coordinates to calculate the result (this is the default). Otherwise, it uses the covariant derivative associated to the metric given as last argument.
