# PetscFVGetCellTabulation
Returns the tabulation of the basis functions at the quadrature points 
## Synopsis
```
#include "petscfv.h" 
PetscErrorCode PetscFVGetCellTabulation(PetscFV fvm, PetscTabulation *T)
```
Not Collective


## Input Parameter

- ***fvm -*** The `PetscFV` object



## Output Parameter

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





## Note
```none
  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
```
