PetscDTAltVInteriorMatrix

Compute the matrix of the linear transformation induced on a k-form by the interior product with a vector

Synopsis

#include "petscdt.h" 
PetscErrorCode PetscDTAltVInteriorMatrix(PetscInt N, PetscInt k, const PetscReal *v, PetscReal *intvMat)

Input Parameters

N - the dimension of the vector space, N >= 0
k - the degree k of the k-forms on which intvMat acts, 0 <= k <= N
v - an N dimensional vector

Output Parameter

intvMat - an [(N choose (k-1)) x (N choose k)] matrix, row-major: (intvMat) * w = (w int v)
