# PetscFVCreateTabulation
Tabulates the basis functions, and perhaps derivatives, at the points provided. 
## Synopsis
```
#include "petscfv.h" 
PetscErrorCode PetscFVCreateTabulation(PetscFV fvm, PetscInt nrepl, PetscInt npoints, const PetscReal points[], PetscInt K, PetscTabulation *T)
```
Not Collective


## Input Parameters

- ***fvm     -*** The `PetscFV` object
- ***nrepl   -*** The number of replicas
- ***npoints -*** The number of tabulation points in a replica
- ***points  -*** The tabulation point coordinates
- ***K       -*** The order of derivative to tabulate



## Output Parameter

- ***T -*** The basis function values and derivative at tabulation 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
```
