# PetscFEGetCellTabulation#

Returns the tabulation of the basis functions at the quadrature points on the reference cell

## Synopsis#

#include "petscfe.h"
PetscErrorCode PetscFEGetCellTabulation(PetscFE fem, PetscInt k, PetscTabulation *T)


Not collective

## Input Parameters#

• fem - The PetscFE object

• k - The highest derivative we need to tabulate, very often 1

## Output Parameter#

• T - The basis function values and derivatives at quadrature points

## Note#

  T->T[0] = B[(p*pdim + i)*Nc + c] is the value at point p for basis function i and component c
T->T[1] = D[((p*pdim + i)*Nc + c)*dim + d] is the derivative value at point p for basis function i, component c, in direction d
T->T[2] = H[(((p*pdim + i)*Nc + c)*dim + d)*dim + e] is the value at point p for basis function i, component c, in directions d and e
