# TSGetTimeError
Returns the estimated error vector, if the chosen TSType has an error estimation functionality. 
## Synopsis
```
#include "petscts.h"  
PetscErrorCode TSGetTimeError(TS ts, PetscInt n, Vec *v)
```
Not Collective, but Vec returned is parallel if TS is parallel

Note: MUST call after TSSetUp()


## Parameters 

- ***ts -*** the TS context obtained from TSCreate() (input parameter).
- ***n -*** current estimate (n=0) or previous one (n=-1)
- ***v -*** the vector containing the error (same size as the solution).
