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)
