# DMPlexMetricCreateUniform
Construct a uniform isotropic metric 
## Synopsis
```
#include "petscdmplex.h"   
PetscErrorCode DMPlexMetricCreateUniform(DM dm, PetscInt f, PetscReal alpha, Vec *metric)
```

## Input parameters

- ***dm     -*** The `DM`
- ***f      -*** The field number to use
- ***alpha  -*** Scaling parameter for the diagonal



## Output parameter

- ***metric -*** The uniform metric





## Note
In this case, the metric is constant in space and so is only specified for a single vertex.
