Tensor handling *** DEPRECATED : use class Tensor instead ***.
const Base_vect * get_triad() const
Returns the vectorial basis (triad) on which the components are defined.
Cmp & set()
Read/write for a scalar (see also operator=(const Cmp&) ).
const Metrique * metric
For tensor densities: the metric defining the conformal factor.
const Map *const mp
Reference mapping.
void set_etat_qcq()
Sets the logical state to ETATQCQ (ordinary state).
void dec2_dzpuis()
dzpuis -= 2 ;
const Tenseur & gradient() const
Returns the gradient of *this (Cartesian coordinates)
friend Tenseur contract(const Tenseur &, int id1, int id2)
Self contraction of two indices of a Tenseur .
void inc2_dzpuis()
dzpuis += 2 ;
int etat
Logical state ETATZERO , ETATQCQ or ETATNONDEF.
