# TaoSetUp
Sets up the internal data structures for the later use of a Tao solver 
## Synopsis
```
#include "petsctao.h" 
PetscErrorCode TaoSetUp(Tao tao)
```
Collective


## Input Parameter

- ***tao -*** the `Tao` context





## Note
The user will not need to explicitly call `TaoSetUp()`, as it will
automatically be called in `TaoSolve()`.  However, if the user
desires to call it explicitly, it should come after `TaoCreate()`
and any TaoSetSomething() routines, but before `TaoSolve()`.


## See Also
 [](ch_tao), `Tao`, `TaoCreate()`, `TaoSolve()`
