PetscDTAltVInterior

Compute the interior product of a k-form with a vector

Synopsis

#include "petscdt.h" 
PetscErrorCode PetscDTAltVInterior(PetscInt N, PetscInt k, const PetscReal *w, const PetscReal *v, PetscReal *wIntv)

Input Arguments

	N	- the dimension of the vector space, N >= 0
	k	- the degree k of the k-form w, 0 <= k <= N
	w	- a k-form, size [N choose k]
	v	- an N dimensional vector

Output Arguments

wIntv -the (k-1)-form (w int v), size [N choose (k-1)]: (w int v) is defined by its action on (k-1) vectors {v_1, ..., v_{k-1}} as (w inv v)(v_1, ..., v_{k-1}) = w(v, v_1, ..., v_{k-1}).
