PETSc version 3.15.5
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 Parameter
|  | 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
