# VecMTDotEnd
Ends a split phase transpose multiple dot product computation. 
## Synopsis
```
#include "petscvec.h"    
PetscErrorCode VecMTDotEnd(Vec x, PetscInt nv, const Vec y[], PetscScalar result[])
```

## Input Parameters

- ***x -*** the first vector (can be NULL)
- ***nv -*** number of vectors
- ***y -*** array of  vectors (can be NULL)



## Output Parameters

- ***result -*** where the result will go





## Notes
Each call to VecTDotBegin() should be paired with a call to VecTDotEnd().
